A 40kg boy is sliding on a horizontal and frictionless surface with an initial momentum of 90J due east. When t=0, a force, a function of time, F=8.20t is applied to the boy due west. a) at what value of t will result in the momentum of the boy 60J due west? b) what is the acceleration of the boy at the time computed in letter a?
