Question

(b) A body of mass 500 g is kept at a height of 5 m. It is allowed to fall and reach
the ground. (g=10 m s?)
(i)
What is the total mechanical energy possessed by the body at the height of
2 m assuming it is a frictionless medium ?
(ii) What is the kinetic energy possessed by the body just before hitting the
ground?​

Answer 1

Answer:

E= mgh

= 500*5*10 = 25000

= 25 J
