A body builder is about to lift a mass of 95 kg. A - What is the weight of the mass if the gravitational field strength on Earth is 9.81 N/kg?

B - If the mass is lifted through a distance of 1.6 m, what is the work done on the mass?

C - Calculate the maximum gravitational potential energy of the weight at this height?

D - The mass is lifted through the height in 2.5 s, what is the personal power of the body builder here?
