Question

At what height above the ground must a mass of 5 kg be to have its P.E.
equal in value to the K.E. possessed by it when it moves with a velocity of
10 m/s? (Assume g = 10 m/s")​

Answer 1

Answer:

let the hight be x

given P.E. should be equal to K.E.

THEREFORE

mgh=1/2mv^2 putting value

5*10*x=1/2*5*(10)^2

=>50x=250

=>x=5m
