Chapter 8, Problem 50SP
Two identical balls undergo a collision at the origin of coordinates. Before collision their scalar velocity components are (ux = 40 cm/s, uy = 0) and (ux = −30 cm/s, uy = 20 cm/s). After collision, the first ball (the one moving along the x-axis) is standing still. Find the scalar velocity components of the second ball. [Hint: After the collision, the moving ball must have all of the momentum of the system.]

Two identical balls undergo a collision at the origin of coordinates. Before collision, their scalar velocity components are (Vx = 42 cm/s, Vy = 0 cm/s) and (Vx = -12 cm/s, Vy = 61 cm/s). After collision, the first ball is standing still. Find the horizontal scalar component of the second ball, expressing your answer in cm/s.
Consider the collision pictured below. While m2 = 10kg is initially at rest, horizontally moving mị = 6kg with a speed of v1 = 11.8m/s collides with it. After the
collision, the two masses scatter with speeds of v, = 7.8m/s and v,. If 01 = 48°, determine the speed of m2 after the collision, v, =?. Express your answer in
units of m/s with one decimal place.
Note: Please note that we do not know whether or not this is an elastic collision.

At time t = 0, the ball is dropped from a height y(0) = ho, where ho is the initial height in meters. It falls freely. At some later time t₁ it hits the ground with a velocity ý(t₁) < 0 m/s (meters per second). A bump event is produced when the ball hits the ground. The collision is inelastic (meaning that kinetic energy is lost), and the ball bounces back up with velocity −ay(t₁), where a is constant with 0 < a < 1. The ball will then rise to a certain height and fall back to the ground repeatedly. The behavior of the bouncing ball can be described by the hybrid system of Figure 1. There is only one mode, called free. When it is not in contact with the ground, we know that the ball follows the second-order differential equation, ÿ(t) = −g, where g = 9.81 m/sec².
