20 minutes to drive between two towns average speed 45 miles per hour how far apart are these towns?
The distance between the two towns is 15 miles. This is determined by multiplying the average speed (45 miles per hour) by the time it takes to drive between the towns (20 minutes converted to hours is 1/3 hour). 45 miles/hour x 1/3 hour = 15 miles.
Explaine what happens to the velocity and the acceleration of an object in fall?
As an object falls freely under the force of gravity, its velocity increases at a constant rate due to acceleration. The acceleration of the falling object is constant and equal to the acceleration due to gravity, approximately 9.8 m/s^2. This means that each second, the velocity of the object increases by 9.8 m/s.
How does mass and speed effect kinetic energy?
Kinetic Energy is 1/2 mass x the square of speed (KE = 1/2 mv^2)
The kinetic energy of a falling object is directly proportional to the distance it falls.
But the distance is not directly proportional to the time in fall, so the KE is not directly proportional
to the time either.
What was the kinetic energy of each car before braking?
More information is needed. Once you have both the mass and the speed, you can calculate kinetic energy as (1/2)mv2 (1/2 times mass times speed squared).

What fields of science study machines?
Fields of science that study machines include robotics, mechanical engineering, computer science, and artificial intelligence. These disciplines investigate the design, development, and functioning of machines to improve their efficiency, intelligence, and capabilities.
What is kinetic energy in the form of?
Kinetic energy is the energy an object possesses due to its motion. This form of energy can be in the form of mechanical energy, thermal energy, or electromagnetic energy, depending on the type of motion involved.
Are systems at lower potential energy more or less stable than systems at higher potential energy?
At lower energy, a system is more stable. At a higher energy, the system will have a tendency to achieve a lower energy. For example, a ball tends to roll down a slope, a compressed (or extended) spring tends to relax.

What characteristic is associated with potential energy rather than kinetic energy?
Position or height is a characteristic associated with potential energy rather than kinetic energy. The higher an object is positioned above the ground, the greater its potential energy.
Top speed of a 2010 Yukon XL Denali?
The top speed of a 2010 Yukon XL Denali is electronically limited to around 130-135 mph for safety reasons. It is important to adhere to speed limits and drive responsibly.
A car travelling 50 kilometers per hour would take how long to cover 60 meters?
To convert speed to meters per second, we divide by 3.6 (1 km/h = 1000 meters / 3600 seconds). Thus, a car traveling at 50 km/h is 13.89 m/s. To find the time taken to cover 60 meters, we use the formula time = distance / speed, which is 60 meters / 13.89 m/s = 4.32 seconds.
How long would it take you to travel 60 miles at 100 miles per hour?
At 60 mph it would take 3.41 seconds to cross an American football field.
How long would it take to go 238857 miles if you were going 55 miles per hour?
A really long time; about six months at 55 miles per hour.
Fnet = F1+F2
Force of man f1 = 10n
Force of goat f2 = 10n
So,
Fnet = 10+10
Fnet=20n
================================
-- If Fred and the man are both pushing in the same direction, then
the net force is 20 newtons.
-- If they're not both pushing in the same direction, then the net force
is less than 20 N, but we don't have enough information to be able to
nail down either the net force or its direction.
The moment a ski jumper lands has all of his potential energy been changed to kinetic energy?
No, not all of the potential energy has been changed to kinetic energy. Some of the potential energy will be dissipated as heat due to air resistance and friction between the skis and the snow upon landing.
A plane climbs into the jet stream which is flowing at a rate of 80 miles per hour Traveling with the jet stream for 5 hours the plane covers 1150 miles The plane then reduces its altitude and flies 150.
If the Kinetic Energy equals five what would the Potential Energy equal?
Kinetic energy and potential energy are not usually proportional. In the general situation, you can't derive potential energy from kinetic energy. In specific cases, sometimes you can - especially if you assume that potential energy that existed previously got converted to kinetic energy, or vice versa.

What happened to kinetic energy is speed is halved?
The formula for kinetic energy is: KE = mv^2, in which m is mass in kilograms and v is speed in meters/second, or m/s. The unit for kinetic energy is the Joule (J), which is one kilogram·m^2/s^2. If the speed of a mass is halved, it's kinetic energy will be reduced by one quarter. For example, if a 1 kg mass has a speed of 4 m/s, its kinetic energy = 1 kg(4 m/s)^2 = 16 J. If the speed of the 1 kg mass is halved to 2 m/s, its new kinetic energy = 1 kg(2 m/s)^2 = 4 J.
What the difference between the acceleration of a baseball one earth compared to the moon?
The acceleration due to gravity on Earth is approximately 9.81 m/s^2, while on the moon it is only 1.62 m/s^2. This means that a baseball will accelerate more slowly on the moon compared to Earth due to the lower gravitational force.
What source does kinetic energy come from?
Motion. The motion can be energized by virtually any source of energy.
What type of energy is used to get the roller coaster car up the first hill?
Potential energy is used to get the roller coaster car up the first hill. The potential energy is converted to kinetic energy as the car goes down the hill. The potential energy is typically provided by a motor or chain lift system.
3 What type of energy is gained as the roller coaster car goes up to the top of the first hill?
Potential energy is gained as the roller coaster car goes up to the top of the first hill. This type of energy is due to the car's height above the ground and its potential to do work as it moves downhill.
The inertia of a bowling ball is what the inertia of a basketball?
No, the inertia of a bowling ball is greater than the inertia of a basketball due to the bowling ball's larger mass. Inertia is the resistance of an object to changes in its state of motion, and a heavier object like the bowling ball requires more force to accelerate or decelerate compared to the basketball.
What is an example of kinetic energy transferred to potiental energy?
Any object which is moving from a lower level to a higher level is converting kenetic energy (ie climbing a set of stairs for example) to potential energy. A car which has been parked at the top of a hill has used kenetic enegry to get up there and has potential to roll down to the bottom of the hill if the brake is released.
