Problem
A 0.25kg cart moves along a track with an initial velocity of 1.2ms−1 to the right. It then experiences the following net horizontal force sequence: +50 N (to the right) for 0.010 s, followed immediately by −30 N (to the left) for 0.020 s. Determine the cart’s velocity immediately after the 0.030 s interval. Indicate the direction of motion in your answer.
