What is the average power the motor must produce to cause this acceleration?

Question

A car accelerates from rest to a speed of 18.0m/s in 6.00 seconds. If the car weighs 16,0000N, what average power must the motor produce to cause this acceleration?

Can you please show me how to do this.
Thanks.

Answer 1

Average power = work divided by time

the work will equal the kinetic energy of the car at 18 m/s since it started from rest. The time is 6 seconds.

.5*16,000N*18^2 is the energy
