Problem
A 0.50kg puck on a nearly frictionless horizontal surface is pulled by a string that exerts a constant horizontal force of magnitude 8.0N. The puck starts from rest, and the force acts for 1.5s.
(a) Calculate the speed of the puck at the end of the 1.5s interval.
(b) Determine the magnitude of the impulse delivered to the puck by the string during this interval.
(c) State the direction of the impulse vector relative to the puck’s motion and explain your answer.
