Given, height = 5m, mass= 200g(0.2kg).
KE = mgh
= 0.2 * 9.8 * 5
= 9.8
Hope this helps!
KE = mgh
= 0.2 * 9.8 * 5
= 9.8

It’s kinetic energy when it just reaches the ground is nothing but it’s potential energy at that height.
K.E = mgh
= (200 × 10^-3 kg) × (9.8 m/s^2) × 5 m
= 9.8 Joule
K.E = mgh
= (200 × 10^-3 kg) × (9.8 m/s^2) × 5 m
= 9.8 Joule
