Answer :
Power=Work/Time
The work done is the energy required to lift the box, fighting the force of gravity. So, Work=Potential energy of the box at 10 meters.
W=PE=mgh=(60)(9.8)(10)=5880J
Finally,
P=W/T=(5880)/(5)=1176Watt
So the answer is 1176 Watts

Answer: 1,200Watts
Explanation:
Power is defined as the rate of change in work done.
Mathematically, Power = Workdone/Time
Since work done = Force × Distance
Power = Force×Distance/Time
Given mass = 60kg
Since we are given mass, we will convert it to force using;
F= ma = 60×10 = 600N
Distance = 10meters
Time = 5seconds
Substituting the values in the formula for power, we have;
Power = 600×10/5
Power = 6000/5
Power = 1,200Watts
Therefore, 1,200 watts is required to complete the work
