Explanation:
Momentum = mass * velocity
So if a tennis ball and table tennis ball have the same momentum then:
M(table tennis) * V(table tennis) = M(tennis)* V(Tennis)
As the table tennis ball is lighter than the tennis ball, table tennis ball has to be faster than tennis ball, for their momentum to be same.
Kinetic energy = ½mv²
As table tennis ball has higher velocity, it will also have higher kinetic energy.
