What is the formula for converting kph to mph?
To convert kilometers per hour (kph) to miles per hour (mph), you can use the formula: 1 kph = 0.621371 mph. So, to convert kph to mph, you simply multiply the speed in kph by 0.621371.
Well, the equation for momentum is mass x velocity. So, p (momentum)= m x v. The equation for kinetic energy is m x v(squared)/2. Let's say that there are two objects. One is 50 kg, and the other is 30 kg. These objects can both have the same kinetic energy, even though one of them has a larger mass. The determining factor in them both having the same kinetic energy, even though one of them has a larger mass is because of different velocities. The 50 kg object has a velocity of 7 meters/second, and the 30 kg object has a velocity of 9.036961141 meters/second. If you do the math, they both have the same kinetic energy (about the same). 50 kg x 7 m/s = 350 kg x m/s. 30 kg x 9.036961141 = 271.1088342. There is an inverse relation between the momentum of an object and its mass. The mass is the factor that influences momentum more than the velocity; that is why an object with a greater mass will have a greater momentum than the one with a lesser mass, only if they both have the same kinetic energy.
How do you calculate distance when given velocity and weight?
To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.
Does a horizontal line on a velocity vs time graph mean an object has stopped?
Not necessarily. If the horizontal line is laying on top of the x-axis, then the
speed is zero at any time, and the object isn't moving. But if the horizontal
line is parallel to the x-axis, then the object is moving with constant speed.
What mph do you get driving 528 feet in 90 seconds?
To calculate the speed in mph, first convert 528 feet to miles (1 mile = 5280 feet), which equals 0.1 miles. Next, divide the distance by the time in hours (90 seconds = 1.5 minutes = 0.025 hours). So, 0.1 miles / 0.025 hours = 4 mph.
Yes, if the car with the greatest speed doesn't cross the finish line first. A car with lower speed starting out may gain enough speed so that at the end of the race it's speed is faster than the other racer, but may not be able to catch up before the other car crosses the finish line.
At 60 miles per hour in 6 seconds how many feet will you travel?
At 60 miles per hour you will travel 528 feet every six seconds.
What vector represents the distance and direction of an objects change in position?
The displacement vector represents the distance and direction of an object's change in position. It is a directed line segment that joins the initial and final positions of the object.
What does MACH 1 have to do with sonic booms?
Mach 1 is the speed of sound. When an object travels at Mach 1, it is moving at the speed of sound. Sonic booms occur when an object travels faster than the speed of sound, creating a shockwave as it breaks the sound barrier.
How do you figure the percent of increase from 55 mph to 70 mph?
To find the percent increase from 55 mph to 70 mph, you first calculate the difference between the two speeds: 70 mph - 55 mph = 15 mph. Then, divide this difference by the original speed (55 mph) and multiply by 100 to get the percent increase: (15/55) * 100 ≈ 27.27%.
How do gravity and potential energy work together to give you a great ride on a roller coaster?
the gravitational potential energy of a roller coaster is equal to two things. Not only is it equal to the gravitational potential energy, it is also equal to the kinetic energy at the lowest point of the coaster.
the gravitational potential energy can be calculated as: m*g*h where m is mass (kilograms), g is gravity (9.8 m/s^2), and h is height (metres).d
the kinetic energy at the bottom of the coaster can be calculated as (m*v^2)/2 where m is mass (kilograms), v is velocity (metres/second).
Is a falling walnut potential or kinetic energy?
No, it's just a simple walnut. But as it falls, some of the potential energy it had
before it fell changes to kinetic energy, and the longer it falls, the more of that
conversion takes place.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
How many miles per hour is 90 km per hour?
V = ( 90 km/hr)( 1000 m/km ) ( 3.2808 ft/m )( 1 mi/5280 ft ) = 55.9 mph <------
___________________________________________
1 mile = 1.609 km
90 km/hour = 90/1.609 miles/hour = 55.935 miles/hour
Which is not a factor in either kinetic or potential energy?
Temperature is not a factor in either kinetic or potential energy. Kinetic energy is dependent on an object's velocity, while potential energy is related to an object's position in a force field. Temperature does not directly impact these forms of energy.
How can you change a C3 from kph to mph?
The legal method to change the KPH to MPH in a Renault Laguna would be to remove the speedometer instrument cluster and take it or ship it to an speedometer and instrument cluster service center where they can legally alter the MPH and KPH with all of the proper paperwork and documentation. Hope this helps!
Nelly's speed is not officially documented, but reports suggest that he has a quick and agile running ability, likely due to his training and athleticism.
How do you increase the potential energy of a wagon without increasing its mass?
You can increase the potential energy of a wagon by lifting it to a higher elevation. This increases its gravitational potential energy without changing its mass.
Who has the most kinetic energy a person running in a race or a plane in flight?
A plane in flight would have more kinetic energy than a person running in a race. This is because kinetic energy is directly proportional to an object's mass and velocity, and a plane's mass and velocity are much greater than that of a person.
Does a plant have kinetic energy?
Plants do produce energy.
Photosynthesis is the process of using photons of light to produce glucose, the plant's energy source.
how can it prouce energy tell the steps to understand it u noob.
A Kawasaki KX85 dirt bike is designed for off-road use and can reach speeds of up to 65-70 mph, depending on various factors such as rider weight, terrain, and maintenance. However, it is important to ride safely and within the legal speed limits of the area.
How long does it take for something moving at 94 miles per hour to go 60 feet?
The equasion I used to figure this out is
475200 / 3600 = 60 / X
An object travelling a steady speed of 90 MPH will travel 475200 feet in one hour. There are 3600 seconds in one hour (475200 / 3600). We are trying to find out how many seconds it takes for an object travelling 90 MPH to go 60 feet (60 / X). By cross multipling, we come up with 475200X = 216000. Dividing 475200 into 216000 gives us .4545454545. This means an object travelling 90 MPH will take .4545454545 seconds to travel 60 feet.
What does it mean when final and initial velocity are the same?
When the final and initial velocities are the same, it means that the object's velocity hasn't changed over time. This could indicate that the object is at rest or moving at a constant speed in a straight line.
