Unformatted text preview: (2 points)A 100kg running back runs with a velocity of 6 m/s towards a stationary 95kg defensive back. After the running back collides with the defensive back, what will be the new combined velocity assuming momentum is conserved and that it is an inelastic collision? 2. (2 points) A 92kg receiver running at 8 m/s catches a pass across the middle and is immediately brought to a stop during a collision with a safety that lasts 0.6 seconds. How much force did the receiver experience? 3. (2 points)Beginning with a vertical velocity of zero, a highjumper pushes off from the ground for 0.3 seconds and leaves the ground with a vertical velocity of 7 m/s. The jump caused a vertical ground reaction force of 1822.7 N. Based on your understanding of ground reaction forces, what is the mass(kg) of the jumper (round to nearest whole number)?...
