The energy required to accelerate a car from 10 m/s to 20 m / s is how many times the energy required to accelerate the car from rest to 10 m /s

The energy required to accelerate a car from rest to 10ms-1 is W .the energy required to accelerate the car from 10ms-1 to 20ms-1 is

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 :

The ratio of energy required to accelerated a car from rest to 20ms^(-1) to the energy needed to acceelerate from 20ms^(-1) to 40ms^(-1) is

A driver decreases the speed of a car from 25 m/s to 10 m/s is 5 seconds. Find the acceleration of the car.
