Question

if momentum of an object is incresed by 20% then k.E

Answer 1

Answer:

1. then K. E decreases by 10 percent.

Answer 2

: If momentum increases by 20 percent, what is the increase in kinetic energy?

If the change in momentum is not due to change in mass then p^2 will change by a factor of 1.2 x 1.2 = 1.44 and so will the energy. So if momentum increases by 20% then kinetic energy will increase between 20 and 44%
