Question

30. A ball of mass 200 g falls from a height of 5 metres. What is its kinetic energy when it just reaches the​

Answer 1

Answer:

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
