Chance · Answer 1

F = 600 N, the applied force

a = 0.08 m/s², the acceleration

t = 1 min = 60 s, the duration

Calculate the distance traveled.

s = (1/2) at²

= 0.5 * (0.08 m/s²) * (60 s) ²

= 144 m

Because the force remains constant, the work done is

W = f*s

= (600 N) * (144 m)

= 86400 J

The average power is

Pavg = (86400 J) / (60 s) = 1440 W

Answer: 1440 W
