Question

A stone having a mass of 300 gm is falling from a height. How much kinetic energy does it have at the moment when it's velocity is 3 m/s?​

Answer 1

Answer:

Example with a mass of 250 gm  

Mass=250gm we have to change in kilometers.

So, 0.25km

Velocity =2 m/s

1/2×m×v2

=1/2×0.25×2×2

=0.50J
