vuject is increased by 10% then its kinetic energy will increase by
(1)30%
(2) 21%
(3)40%
(4) 19%​

Answer 1

Answer:

If one increases the momentum by 10% the kinetic energy will naturally increase. so one can say that the KE will increase by 21%. Momentum = velocity × mass. I'm assuming mass stays constant throughout the transformation, so the difference in momentum is due to changes in velocity.
