Question

A stone having a mass of 500 gm is falling from a height. How much kinetic energy does it have at the

moment when its velocity is 2m/s2

​

Answer 1

Answer:mass =250gm =250/1000 =1/4 kg

velocity =2m/s

K.E. =1/2mv²

=) 1/2*1/4*2*2

=) 1/2joules

Answer 2

Explanation:

kinetic energy =1/2 mv²

1/2*0.5kg*2*2

=1 kg m/s

=1 joule

hope it helps
