Answer:
Concept: Physics
- Power is related to Work which we will find below
- [tex]work = f \times d[/tex]
- 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
- [tex]p = \frac{w}{t} [/tex]
- Hence
- [tex] \frac{1960}{10} [/tex]
- So we get that P= 196 W
