A car of mass 750kg accelerates away from traffic lights. At the end of the first 100m it has reached a speed of 12 m/s. During this time, its engine provides an average forward force of 780 N, and the average force of friction on the car is 240 N. Calculate the increase in the car's kinetic energy at the end of the first 100 m

Answer:

the answer according to me is 54000j

Step-by-step explanation:

im not sure why the force and friction are given inthe question because the the formula of ke is 1/mv^2
