Problem
A 0.50kg air-track glider moves along a straight line. At t=0s its linear momentum is 1.0kg⋅m/s in the +x direction. At t=4.0s its momentum is 5.0kg⋅m/s in the +x direction. Assume the momentum changes at a constant rate during the interval.
(1) Calculate the magnitude and direction of the net external force acting on the glider during the 4.0 s interval.
(2) Determine the glider’s acceleration during this interval.
(3) If the glider’s speed at t=0s is 2.0m/s, determine its speed at t=4.0s. Show that your result is consistent with your answer to part (a).
