1. Collision. Two identical billiard balls collide head-on to each other as shown. The incident velocities vi and v2 (before collision) are 3 m/s and 7 m/s (pay attention to their directions). a). What is the value of the velocity of the center-of-mass of the system? b). In the center of mass reference frame, the velocities of two objects are denoted as v' and v2'. Please find the values of v' and v2 e). In the center of mass reference...

Two 1.8 kg bodies, A and B, collide. The velocities before the collision are A = (12 + 25) m/s and B = (-10 + 10.0) m/s. After the collision, 'A = (-1.0 + 22) m/s. (a) What is the final velocity of B? = m/s (b) What is the change in the total kinetic energy (including sign)? J
Learning Goal: To use the conservation of momentum and the coefficient of restitution to determine the speeds of two disks after a collision Two disks collide with the initial velocities just before the collision as shown in (Figure 1). What are the speeds of the two disks just after impact if the coefficient of restitution is e = 0.9? The masses of the disks are mA = 5 kg and mB = 7.5 kg, the initial velocities are vA = 3...
1. Two billiard balls (a striped and a solid) collide head on. Prior to the collision the striped ball had a momentum of 6 kg m/s and the solid ball had a momentum of 20 kg m/s. After, the collision the solid ball comes to rest. How much momentum does the striped ball have and which way is it moving? 32. A 10 kg rock is 4 m above the ground and moving at 22 m/s. Calculate how much PE...
A 3-kg hard steel ball collides head-on with a 1-kg hard steel ball. The balls are moving at 2 m/s in opposite directions before they collide. Upon colliding, the 3-kg ball stops. What is the velocity of the 1-kg object after the collision? ( Hint: Assign velocities in one direction as positive; then any velocities in the ooposite direction are negotive.)
1. Two asteroids collide head-on and stick together. Before the collision, asteroid A (mass 1,000 kg) moved at 100 m/s and asteroid B (mass 2,000 kg) moved at 80 m/s in the opposite direction. Use momentum conservation (make a complete Momentum chart) to find the velocity of the asteroids after the collision. 2. Two asteroids identical to those in (1) collide at right angles and stick together. "Collide at right angles" means that their initial velocities were perpendicular to each...
Problem 10: Two 1.0-kg balls, A and B, move as shown in the figure and collide. During the collision, half the kinetic energy A is lost. After the collision, ball A is going straight in the vA3m/s V- 2 m/s negative y direction. Find A and B's final velocities. Problem 10: Two 1.0-kg balls, A and B, move as shown in the figure and collide. During the collision, half the kinetic energy A is lost. After the collision, ball A...
