A car of mass 1000 kg accelerates uniformly from rest to a velocity of 15 m/s in 5 sec. The average power of the engine during this period in watts is :

A

2000W

B

22500W

C

5000W

D

2250W

Text Solution

Verified by Experts

`F=1000((15-0)/(5))=3000N`
`ltPgt `ltPgt = ([(1)/(2)(1000)(15)^(2)-0])/(5)=22500" Watt"`
