1. A 50.5 kg quarterback is running with a football downfield at a speed of 2 m/s and is tackled by another player with a mass of 70 kg running toward him at 4 m/s. When the tackler grabs the quarterback, they both fall backward at the same speed of 1 m/s (opposite to the original direction of the quarterback). In the process, the 0.5 kg football comes loose at the moment the collision takes place.
a) Calculate the velocity of the fumbled football.
b) What is the impulse delivered to the quarterback? (Do not include the mass of the football).
c) If the impact of the tackle lasts for 0.1 second, then find the average force of the tackler on the quarterback.
