Solution

The correct option is A 100 %
When the kinetic energy increases by 300%,new kinetic energy will be
K=K+300%K
K=K+3K
K=4K.............(i)
We know that,
K.E, K=P22m 9m is the mass of object0
Therefore, eq.(i) become
P22m=4p22mp2=4p2p=4p2p=2p...........(ii)
% change in momentum =ppp×100
=2ppp×100%=1×100=100%
Therefore, increases in momentum is 100%.
