Answer:
height = 5m
height = 5mmass = 200g
height = 5mmass = 200gpotential energy = mgh = 0.2 ∗ 5 ∗ 9.8 = 9.8J
height = 5mmass = 200gpotential energy = mgh = 0.2 ∗ 5 ∗ 9.8 = 9.8JSince potential energy at the highest point is equal to kinetic energy at lowest point , therefore kinetic energy will be 9.8J
.hope it helps u!

Correct option is
A
9.8J
height = 5m
mass = 200g
potential energy = mgh = 0.2 ∗ 5 ∗ 9.8 = 9.8J
Since potential energy at the highest point is equal to kinetic energy at lowest point , therefore kinetic energy will be 9.8J
