How much power is used to move a 25 kg mass 8 meters in 15 seconds?
Answers: 2
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 
Hence 
So we get that P= 196 W
