Question

A ball of mass 200 grams falls from a height of 5 metres calculate its kinetic energy when it just reaches the ground G is equals to 10 ms-2
second​

Answer 1

Height = 5m.

Mass = 200g (0.2 kg)

g = 9.8m/s^2

∴ Potential energy = mgh

                        = 0.2*5*9.8

                        = 9.8 J

∵ P.E at the highest point = K.E at the lowest point (when it is just about to hit the ground)

∴ K.E energy will be= 9.8 J

Hope this helps.... : )

Answer 2

hey mate

9.8 j will be the answer. ......
