Divide the kinetic energy increase (in Joules) by 7.0 s. The ratio will be the average power in watts.
Make sure you convert 95 km/h to 26.4 m/s before computing the kinetic energy
A 1300 sports car accelerates from rest to 95KM/H in 7.0S .What is the average power delivered by the engine?

change km/h to m/s
power= 1/2 m v^2/time
power= 1/2 m v^2/time
