Hey!

_____________


Original Kinetic energy = 1/2 mv^2

Velocity halved
v = 1/2

New kinetic energy = 1/2 × m × 1/2 v^2
= 1/4 mv^2

New kinetic energy will be 1/4th of the first one.

Hope it helps...!!!

Heya.....!!!

_______________

Original Kinetic Energy ( say K1 ) = 1/2×m×v²

If velocity is halved i.e = v/2

Then , new Kinetic Energy ( say K2 )
=> 1/2×m× (v/2)²

K2 = 1/2 ×m ×v²/4 → 1/4 × 1/2 ×m×v²

So ,, New Kinetic Energy ( K2 ) will ' 1/4 ' of original Kinetic energy ( K1 ) .
