Respuesta :
Power is energy/time, where t is seconds. Assuming you were moving the box the whole time, you did 3150/(5*60) = 10.5W
Answer:
10.5w
Explanation: power is the ratio of work done in joule with time in seconds.
Therefore,
Power = work done/time
Work done = 3150j
Time = 5×60 = 300s
Power = 3150/300
= 10.5W
