49 J, Find the height

please answer me ​

Answer 1

Answer:

Energy possess by body at height 5m =)

Potential energy =) m*g*h

= 1* 9.8 * 5 u may take g = 9.8 m/s^2 or 10

= 49J

According to law of conservation of energy....

Energy possess by body remains constant until when no external force acts on it..

Hence 49J is correct answer.

Hope it's helpful to u.
