Question

A ball is thrown up vertically with a velocity of 20 m/s, at what height will its kinetic energy be half it's original volume ?

Answer 1

Let h be the height at which the kinetic energy will be half of its original value that means at that height remaining half is converted into potential energy .

K.E= 0.5*m*400 =200*m

at H=h,

P.E= 0.5*K.E

m*g*h=100*m

h=100/g= 10.1936 meters
