A car of mass 1,700 kg is initially traveling at a speed of 25 m/s. The driver then accelerates to a speed of 35 m/s over a distance of 500 m. Calculate the change in the kinetic energy of the car.

Answer 1

The initial speed is V1 = 25 m/s
The final speed is V2 = 35 m/s
The mass M = 1700 kg does not change.

Compute (M/2)(V2^2 - V1^2)

The distance over which the acceleration happens does not affect the answer.
