uring sprinting, the propulsive impulse lasts 3 times longer than the breaking impulse. The breaking impulse lasts 0.06 seconds. As a result of the breaking impulse, the horizontal velocity decreases by 1.0 m/s and the vertical velocity decreases by 1.3 m/s. During propulsion the 75 kg individual is trying to increase their horizontal velocity by 1.6 m/s and their vertical velocity by 1.5 m/s. What are the average horizontal GRF values needed during both the breaking and propulsive phases to ensure the runner achieves their desired result during the stance phase if the coefficient of friction between the shoe and the track is 0.22

A 2.0-kg box is attached by a string to a 5.0-kg box. A compressed spring is placed between them. The two boxes are initially at rest on a friction-free track. The string is cut and the spring applies an impulse to both boxes, setting them in motion. The 2.0-kg box is propelled backwards and moves 1.2 meters to the end of the track in 0.50 seconds. Determine the time it takes the 5.0-kg box to move 0.90 meters to the opposite end of the track.
