63. Two billiard balls of identical mass move toward each other. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are 30 cm/s and -20 cm/s, assume friction and rotation are unimportant What are the velocities of the balls after the collision? Find the final velocity of the two balls if the ball initial velocity of -20 cm/s has a mass equal to one half of the ball with initial velocity 30 cm/s

2- Two identical billiard balls may move freely on a horizontal table. Ball A has a velocity of 0.4 m/s as shown, and hits ball B, which is at rest, at point C defined by ? = 40° (the line of impact is along 40° path with respect to the horizontal direction). Assuming no friction, and knowing the coefficient of restitution between the two balls is 0.75, determine the velocity of each ball after impact.

Collisions and Kinetic Energy ** Two billiard balls are initially traveling toward each other with Ball 1 having a velocity of 2.00 m/s to the right and Ball 2 having a velocity of 8.00 m/s to the left. The balls undergo an elastic, head-on collision. Find their final velocities. (Define the positive direction to be to the right.) Part 1 + First consider two identical objects with equal mass, one is at rest and the other has a velocity of...

Two billiard balls with identical masses of 1 kg move toward each other. The initial velocity of ball 1 is +30 cm/s and the initial velocity of ball 2 is -20 cm/s. The final velocity of ball 1 is -20 cm/s and the final velocity of ball 2 is +30 cm/s. Assume friction and rotation are unimportant. Show, through conservation of energy, that this was indeed an elastic collision. (Hint: Find the kinetic energy of the system before and after...

Suppose we have two urns (a left urn and a right urn). The left urn contains N black balls and the right urn contains N red balls.
Suppose we have two urns (a left urn and a right urn). The left urn contains N black balls and the right urn contains N red balls. Every time step you take one ball (chosen randomly) from each urn, swap the balls, and place them back in the urns. Let Xm be the number of black balls in the left urn after m time steps. Find the Markov chain model and find the unique stationary distribution when N=5
