tanushree6794: It will be increased by 21% Let the initial mass of the body be m and its velocity be v. Initial momentum of the body mv Initial KE mv^2/2 If the momentum increases by 10%, new momentum mv 10 % of mv mv 10/100mv = mvmv/10 =11mv/10 m(11 /10) New velocity = 11v/10 Increase in velocity v/10 New KE m(11v/10)^2/2 121/100mv 2/2 Increase in KE 21 %
