How far will you travel at 70 mph in 1 second?

User Avatar

Asked by Wiki User

At 70 mph, you would travel approximately 102.67 feet in 1 second. This calculation is based on the formula: speed (in miles per hour) / 3600 * time (in seconds) = distance (in feet).

What is the speed of 34mph in meters per second?

User Avatar

Asked by Wiki User

To convert 34 mph to meters per second, you can use the conversion factor 1 mph = 0.44704 m/s. Therefore, 34 mph is approximately equal to 15.2296 m/s.

What is the difference between potential and kinetic energy in a ven diagram?

User Avatar

Asked by Wiki User

Potential energy is energy stored in an object due to its position or state, such as gravitational potential energy or elastic potential energy. Kinetic energy is the energy an object possesses due to its motion. In a Venn diagram, potential energy would be shown in one circle, kinetic energy in another, with the overlapping area representing objects that have both potential and kinetic energy simultaneously.

How do you calculate time when given distance and initial velocity?

User Avatar

Asked by Wiki User

To calculate time when given distance and initial velocity, you can use the formula: time = distance / initial velocity. Simply divide the distance by the initial velocity to find the time it takes to travel that distance at the given speed.

Does a jet plane at the point of taking off have kinetic energy or potential enegery?

User Avatar

Asked by Wiki User

At the point of taking off, a jet plane has kinetic energy. This is because the airplane is in motion and has energy due to its movement. Potential energy would be present when the airplane is stationary on the ground, stored in the form of gravitational potential energy.

Is it possible for an object to move for 10 seconds at a high speed and end up with an average velocity of zero?

User Avatar

Asked by Wiki User

Yes, it is possible. If the object moves in opposite directions for half the time at the same high speed, then the displacements cancel out, resulting in an average velocity of zero over the 10 seconds.

Why is potential energy is defined in massxgravityxheight?

User Avatar

Asked by Wiki User

Potential energy is defined as mass × gravity × height because it represents the energy stored in an object due to its position above the ground. The mass accounts for the quantity of matter, gravity represents the acceleration due to gravity, and height indicates the distance the object is lifted from the ground. Multiplying these factors provides a measure of the potential energy stored in an object when it is raised to a certain height.

How fast will a man travel 556 feet at 1.7 mph?

User Avatar

Asked by Wiki User

At a speed of 1.7 mph, a man will travel 556 feet in approximately 10 minutes.

What happens to kinetic energy if the mass is doubled?

User Avatar

Asked by Wiki User

If mass is doubled while velocity remains constant, the kinetic energy will also double since kinetic energy is directly proportional to the mass. This is because kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2.

Would you get a ticket for driving 75 kilometers per hour in a 55 miles per hour speeding zone?

User Avatar

Asked by Wiki User

Yes, driving 75 kilometers per hour is equivalent to approximately 46 miles per hour, which is still over the posted speed limit of 55 miles per hour. Therefore, you would likely still receive a speeding ticket for driving 46 miles per hour in a 55 miles per hour zone.

How many feet per second you travel at 38 mph?

User Avatar

Asked by Wiki User

At 38 mph, you would be traveling at approximately 56 feet per second. This can be calculated by converting miles per hour to feet per hour (38 mph = 56 feet per second) and then dividing by 3600 to convert hours to seconds.

How many miles per hour is 200 meters in 36 seconds?

User Avatar

Asked by Wiki User

200 meters in 36 seconds is equivalent to a speed of approximately 18.18 miles per hour.

Is there any change in the vector if there is change in angle?

User Avatar

Asked by Wiki User

Yes, changing the angle of a vector will result in a change in its direction. The magnitude of the vector remains the same, but the direction it points in will be different.

What will be the acceleration of a car moving in a uniform acceleration?

User Avatar

Asked by Wiki User

The acceleration of a car moving with uniform acceleration will remain constant. This means that the rate of change of its velocity will be consistent over time, resulting in a steady increase or decrease in speed.

How many miles can you go in five Hr at 65 MPH?

User Avatar

Asked by Wiki User

You can travel 325 miles in five hours driving at a speed of 65 miles per hour (65 mph x 5 hr = 325 miles).

How many feet per second does a longbow shoot?

User Avatar

Asked by Wiki User

A longbow can shoot arrows at speeds ranging from 150 to 180 feet per second, depending on factors such as the draw weight of the bow and the type of arrow used.

How many feet did you travel going 70 mph in 20 seconds?

User Avatar

Asked by Wiki User

If you're going 70mph, which is:

70 miles/hour x 5280 feet/mile = 369,600 feet/hour .... we can use this to find how fast you're moving in feet per second.

369,600 feet/hour x 1 hour/3600seconds = 102.667 feet/second

So in 20 seconds you will have traveled 102.667 * 20 = [2053.34 feet]

What is the kinetic energy of a 2000kg car moving at 50 mph?

User Avatar

Asked by Wiki User

The formula for calculate the energy with in a moving object is :1/2mv.v solution:m=2000 kg v=70 m/h = 70 x 1609.3 m/hr = 112649 m/hr = 112649 / 3600 m/s = 31.3 ms-1 energy=1/2 x 2000 x 31.32 Js-1 = 979690 J = 979.69 kJ

What is the measurement mach?

User Avatar

Asked by Wiki User

Mach is the speed of sound in that medium, and is known as Mach 1. It will vary according to pressure and temperature. [More correctly, it is the dimensionless number relating the speed of an object to that of sound in that medium.] Mach does not have units associated with it, such as mph or kmph.

How fast is 112 kph?

Asked by Wiki User

112 kph is approximately 69.6 mph.

How many feet traveled in one second doing 60kph?

User Avatar

Asked by Wiki User

At 60 kilometers per hour, the velocity is approximately 16.67 meters per second. So in one second, the distance traveled would be 16.67 meters, which is equivalent to approximately 54.79 feet.

How fast is 2000 meters in 7 minutes and 35 seconds?

User Avatar

Asked by Wiki User

To find the speed, first convert 7 minutes and 35 seconds to seconds only (455 seconds total). Then, divide the distance (2000 meters) by the time (455 seconds) to get the speed: 2000 meters / 455 seconds = 4.40 meters per second.

What kind of energy happens when a roller coaster reaches the very top of the track just brfore it starts back down?

User Avatar

Asked by Wiki User

At the top of the track, the roller coaster has mostly potential energy due to its height above the ground. As it starts back down, this potential energy gets converted into kinetic energy as the coaster picks up speed.
