Question

a 2m tall man , standing at the top of a 30m tall tower , raises a 1kg mass 0.5m above his head . the potential energy of the raised mass may be considered to be . answer with solution
​

Answer 1

is here mate please mark my answer as brainliest please

The formula for potential energy is mg* delta h, where:

m = mass of the object (1 kg)

g = force of gravity (-9.81 m/s^2)

delta h = change in height from a benchmark. I’m not sure if your benchmark for this problem is the man’s feet or the base of the building.

For the first case (benchmark is the man’s feet):

PE = mgh = 1*9.81*2.5 = 24.5 J

For the second case (benchmark is the base of the building):

PE = mgh = 1*9.81*32.5 = 318.8 J
