Answer:

Concept: Physics

  • Power is related to Work which we will find below

  • work = f * d
  • Note that force is a vector quantity that has magnitude and direction
  • We have a mass of 25 kg and we want to know the force it exerts by newton's first law: 25 × 9.81 m/s^2 = 245 N
  • Now we have our force and d
  • 245 × 8 meters= 1960 J
  • Power is represented in joules
  • The equation for Power is

  • p = (w)/(t)
  • Hence

  • (1960)/(10)
  • So we get that P= 196 W
