Answer:

initial mass=m, velocity =v

initial momentum of body =mv

initial K.E.=mv^2/2

if the momentum increases by

10%,

new momentum = mv+10% of

mv

=mv+10/100mv

= mv+ mv/10

=11mv/10

=m(11v/10)

new velocity =11v /10

increase in velocity=v/10

new K.E.=m(11v/10)^2/2

=121/100mv^2/2

increase in K.E.=21%
