Questions
If the momentum of a body is increased by 50%, its kinetic energy will increase by
a
100%
b
125%
c
150%
d
200%
detailed solution
Correct option is B
Let initial momentum be p. increase by 50% implies that new momentum is p+p2 i.e. 32p Since,K=p22m ⇒K∝p2 So, new kinetic energy becomes 9K4 .Percentage increase =(94−1)×100=125%Talk to our academic expert!
