Does the kinetic energy of a car change more when it goes from 10 m/s to 20 m/s or when it goes from 20 m/s to 30 m/s ?

The enrgy The energy reqduired to accelerate a car from 10 m/s to 20 m/s compared with that required to accelerate from 0 to 10 m/sec in the same interval of time overcoming same resistance is :

What force will change the velocity of body of mass 1 kg from 20 m/s to 30 m/s is 2 s?

What force will change the Velocity of a body of mass 1 kg from 20 m// s to 30 m//s in 2 seconds?

A particle moves along an x axis. Does the kinetic energy of the particle increase, decrease, or reman the same if the particle's velocity changes (a) from -3 m//s to -2m//s and (b) from -2 m//s to 2m//s ? (c) In each situation, is the work done on the particle positive, negative, or zero?

Calculate the change in energy for a body of mass 5 kg, change its velocity from 10 m/s to 16 m/s.

If the velocity of a car moving with uniform velocity changes from 20m/s to 40m/s in 5s What is the acceleration of the car?

Calculate the work done by the brakes of a car of mass 1000 kg when its speed is reduced from 20 m/s to10 m/s ?

The kinetic energy of a body of mass 5 kg is 100 J. When it is thrown up then the height to which it goes up, is (g=10m//s^(2))
