Question

A car of mass 1000kg accelerates uniformly from rest to a velocity of 54 km/h in 5sec. The average power of the engine during this period is

Answer 1

Answer:

3000 N or 3000/5 = 600

Explanation:

force = mass * acceleration

a = v - u /t

a = 15 - 0 /5 (54 km/h = 15m/s)

a = 3

f = 1000 * 3 = 3000 N
