weight = (f×s)/t
580×80/60×4=193.33watts
580×80/60×4=193.33watts

Power is work/time=Force x displacement/Time=580x8/(4*60)

force = 580 N
displacement = 8m
work = Force x displacement
= 580 x 8
= 4640 J
now time = 4min = 4x60 s = 240s
power = work/time
= 4640/240 W
= 19.33 W
displacement = 8m
work = Force x displacement
= 580 x 8
= 4640 J
now time = 4min = 4x60 s = 240s
power = work/time
= 4640/240 W
= 19.33 W
