A car of mass 1000kg starts from rest on a level road. A constant engine force of 1500N acts on the car and resistive forces may be neglected for the time interval considered.
a. (i) Calculate the acceleration of the car.
b. (ii) Determine its speed after 8s from the start.
c. (iii) Find the instantaneous power developed by the engine at t=8s.
d. (iv) Compute the average power supplied by the engine during the first 8s.
