Question

An object of mass 50 kg is raised to a height of 4 m above the ground in 2 sec by an agent. Calculate
(A) Potential energy of the object
(B) Power delivered by the agent​

Answer 1

mass(m) = 50kg

time(t) = 2 sec

height(h) = 4m

g = 10m/s²

(Note:value of g is constant)

potential energy = mgh

= 50*10*4

= 2000J

power = potential energy/time

= 2000/2

= 1000W
