Is this correct please ?
The sports car has a mass of 23 Mg and accelerates at
6 m/s, starting from rest. If the drag resistance on the car
due to the wind is Fp- (10p) N, where v is the velocity in
m/s determine the power supplied to the engine when
-Ss. The engine has a running efficiency of e- 0.68.
After 5s, the velocity of car is 30m/s and the power supplied to engine is 423
kW
O After 5s, the velocity of car is 10m/s and the power supplied to engine is 423
kW
After 5s, the velocity of car is 30m/s and the power supplied to engine is 622
kW
O After 5s, the velocity of car is 10m/s and the power supplied to engine is 622
kW
