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