Question

A car is initially traveling along a road at 5 m/s and then accelerates until it reaches 10 m/s, at which point it travels at this constant velocity. If the car has a mass of 1000 kg, how much does its kinetic energy increase from before to after it accelerates to the higher velocity? A. 37.5 kJ B. 25 kJ C. 12.5 kJ D. 50 kJ A car is initially traveling along a road at 5 m/s and then accelerates until it reaches 10 m/s, at which point it travels at this constant velocity.
