Question

If momentum of an object is increased by 10% then its kinetic energy will increase by
(1) 20%
(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. ... Thus a 10% increase in momentum becomes a 21% increase in KE.

So your Answer is

(2) 21%
