So Work= Kinetic Energy and........ (1 Viewer)

Good i also used final velocity not avg velocity in 0.5 x m x v^2 is that ok?

That's what you are supposed to use - the velocity at state 2.

Kinetic energy of something only depends on that instant of measurement. It doesn't care what happens before, so using the average velocity would be meaningless.

Thankyou so much
