Consider a head-on collision between two billiard balls. One is initially at rest and the other moves toward it. Sketch a position VS time graph for each ball, starting with time before the collision and ending a short time afterward. Are momentum and kinetic energy conserved in this collision?
2. Two clay balls collide head-on in a perfectly inelastic collision. The first ball has a mass of 0.5 kg and an initial velocity of 4 m/s to the right. The second ball has a mass of 0.25 kg and an initial veiocity of 3 m/s to the left. Find the velocity of clay balls that stuck together.

Two identical spheres collide. Prior to the collision sphere #1 was moving in the *x direction with a speed of 132 m/s. Prior to the collision sphere #2 was moving in the y direction with a speed of 128 m/s. After the collision sphere #1 comes to an Immediate stop. To the nearest m/s, what is the speed of sphere #2 after the collision A cannon is positioned at the edge of a cliff. A cannonball is fired with an...
1- Billiard ball A with mass 0.81 kg collides head on and elastically with billiard ball B (same mass) at rest. Knowing that Ball A moved at 3.41 m/s before collision, what is the speed of Ball B after the collision? 2- A 4.78 kg cube sits on a frictionless surface. A 11.99 gram bullet traveling at 388.07 m/s is shot into the brick and they move together at a certain speed. What is the speed in m/s? 3- What is...
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 billiard balls of identical masses collide. The red ball was traveling at a velocity of 7 m/sec. The black ball at a velocity of 12 m/sec. If the black ball after impact had a velocity of 5 m/sec, what was the velocity of the red ball after collision? This was all that was given to me. I guessing they are colliding to each other.
Two billiard balls undergo an elastic collision as shown in the figure below. Ball 1 is initially traveling along x with a speed of 15 m/s, and ball 2 is at rest. After the collision, ball 1 moves away with a speed of 7.5 m/s at an angle θ-60°. (For the following questions, assume the mass of ball 1 is equal to the mass of ball 2.) Ball Ball 1 Ball 21/<θ li (a) Find the speed of ball 2...

Two balls collide head-on. The initial velocity of the first ball is 3 m/s, while that of the second is -0.45 m/s. The mass of the first ball is 33 kg and the mass of the second ball is 80 kg. If the collision is perfectly elastic, what is the final velocity (magnitude and direction) of each ball?
