Question

4. A ball of mass 200g falls from a height of 5m. What
is its potential energy when it just reaches the ground?
(g = 9.8 ms)​

Answer 1

Explanation:

Potential Energy (K) = mgh

m = 200g

m = 0.2kg

h = 5m

g = 9.8m/s

K = mgh

K = (0.2)(5)(9.8)

K = (1.0)(9.8)

K = 9.8J

Hope it helps:)

Answer 2

Answer:

Mass=200g = 0.2kg

h=5m

g=9.8m/s^2

Hence..............

   :: Potential Energy (U) = mgh

                                        = 0.2*5*9.8

                                        = 9.8 J
