The red billiard ball in the picture above is initially at rest and is hit by the white ball that initially moves to the right with constant speed and along the lower horizontal dashed line. The red ball is hit 'off center' over a distance d (see picture). There is no friction. The collision is elastic and both balls have the same mass. After the collision the balls move along the red and white lines in the picture. Which of the following statements is not correct? Angle B is always smaller than 90°. O Angle a is always smaller than 90°.

A 2.45 kg ball is shot into a 0.45 kg box that is at rest on a frictionless horizontal table. The box is attached to a 0.30 m long rope that is attached to the table on the other end, as shown in Figure . The ball initial velocity is 13.5 m/s and is perpendicular to the rope. After the collision the ball and the box stick together and move. What is the tension in the rope? 0.30 m

As shown in the figure (Figure 1), a superball with mass m equal to 50 grams is dropped from a height of h₁ = 1.5 m. It collides with a table, then bounces up to a height of hf = 1.0 m. The duration of the collision (the time during which the superball is in contact with the table) is tc = 15 ms. In this problem, take the positive y direction to be upward, and use g = 9.8 m/s² for the magnitude of the acceleration due to gravity. Neglect air resistance.

1. The launcher is set to launch a projectile horizontally. Once launched, the projectile will immediately go into the pendulum (the “catcher” in the diagram), causing the pendulum to swing. Considering momentum, sum all the momenta of the situation after the ball is launched but before it goes into the pendulum. Do not consider the recoil of the launcher. 2. When the ball gets caught by the pendulum, what kind of collision is this (elastic or inelastic)? What is the momentum after the collision? Using conservation of momentum, derive an equation for the velocity of the ball/pendulum combo immediately after the ball is caught (and before the pendulum starts to swing upward). The equation can depend on the mass of the ball, the mass of the pendulum, and the initial velocity of the ball. 3. The pendulum will start to swing upwards. At the beginning of its swing, what kind ofenergy does the pendulum have? It will swing up to a certain angle where it will temporarily stop. What kind of…
