Question

a man of 50kg mass has p.E of 9800j at a certain height from the ground . Find the height from the ground at which its P.E reduced to 2450j?​

Answer 1

Explanation:

4.9 meters

explanation-

P.E=mgh

2450=50×10×h

h=2450÷50×10

h=4.9m

Answer 2

Answer:

4.9m

Explanation:

As G.P.E=mgh

mass = 50 kg

Gravity =10

Potential energy = 2450j

2450=50x10xh

2450= 500 x h

2450\590 = h

Hence,

H= 4.9 metres
