Power =Force * Velocity


Velocity = Distance/Time = 2/0.5 = 4 m/s


Therefore,


P = 1000*4 =  4000 W = 4 kW

Lera25 [3.4K]

Answer:

Power = 24.41Watts

Explanation:

Find the diagram attached

Power output  = Force * distance/Time

Given

Force = 120lb

Distance = 9inches

Time = 5sec

Since

1lb = 4.4482216153 N

120lb  = 120 * 4.4482216153

120lb = 533.787N

9in to meters

9in = 0.0254*9

9in = 0.2286N

Power = 533.787*0.2286/5

Power = 24.41Watts
