Question
On a very muddy football field, a player of mass m₁ tackles a second one of mass
m2 = 3m₁/2. Immediately before the collision, player 1 is slipping with a velocity of v₁ due north
and player 2 is sliding with a velocity of v2 = 2v1 due east.
3a. Sketch the situation, placing careful labels, and write formulae for the initial momenta of the
two players. Might want to chose a coordinate system that will help you figure out how to add
together these momenta.
3b. What is the magnitude of the total momentum of the system of these two players before they
collide?
3c. What are the magnitude and direction of the velocity at which the two players move together
immediately after the collision?
3d. Calculate the loss of kinetic energy associated with this collision.
