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.

The angle between the ball's initial velocity vector and the wall is 6 as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is At, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning.

a. d. Always come back to the example of the tennis ball to remember on which direction you need to apply the coefficient of restitution. Because the bounds are lower and lower and the coefficient of restitution is less than 1, you apply the coefficient of restitution on the axis normal to the plane of contact. For the tennis ball the plane of contact is the floor and the axis normal to the plane of contact is 2. O bigger O lower line 93 impact O the same The components of the velocity on x and y are the same and the component of the velocity on z is after impact. - x 3. plane contact You can also find the line of impact using this definition: The line of impact is a line through the But this definition is hard to use when only one particle collides into a surface. This definition is great to use when 2 balls collide together as this example: O mass centers of the colliding particles. O geometric centers of the colliding particles 10 m/s b. On this example the line of impact is: O…
