a solid sphere is rolling purely on a rough horizontal plane(co.eff of kinetic friction is k)with the speed of center is U.it collides ineleastically with a smooth vertical wall at a certain moment ,the co eff of restitution is 1/2 the sphere will start rolling after time?                                                                                                                    detail explanation please

linear acceleration a =kmg/m =kg


so V/14 = V/2 -at


   V/14 = V/2 - kgt


t = 3V/7kg
