Homework Answers
Let mass of receiver = m
From conservation of momentum,
m1v1 = (m1 + m)*v2
120*3.1 = (120 + m)*1.7
m = 98.82 kg

During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of +4.2 m/s, grabs and holds onto him so that they move off together with a velocity of +2.3 m/s. If the mass of the tackler is 120 kg, determine the mass of the receiver (kg). Assume momentum is conserved.

Two football players collide head-on in midair while chasing a pass. The first player has a 110 kg mass and an initial velocity of 4.10 m/s in the positive x direction, while the second player has a 125 kg mass and initial velocity of 3.40 m/s in the negative x direction. What is the x component of their velocity just after impact if they cling together? (Indicate the direction with the sign of your answer.)
