A billiard ball with a mass of 0.15 kg is moving with a velocity of < 5, 0, 0 > m/s. It collides with a 2nd billiard ball of mass 0.20 kg initially moving at < -7, 0, 0 > m/s. After the collision, you observe the 2nd billiard ball moving at < 0.13, 0, 0 > m/s. a) What is the velocity of the 0.15 kg billiard ball after the collision? b) What is the vector change in momentum...

A racquet ball with mass m = 0.252 kg is moving toward the wall at v = 18.2 m/s and at an angle of θ = 25° with respect to the horizontal. The ball makes a perfectly elastic collision with the solid, frictionless wall and rebounds at the same angle with respect to the horizontal. The ball is in contact with the wall for t = 0.06 s. 1) What is the magnitude of the initial momentum of the racquet...
2. Two steel balls are colliding elastically. Ball 1 has a mass of 1.20 kg and is moving 3.00 m/s at an angle of 45 degrees measured from the positive X-axis before the collision. Ball 2 has a mass of 1.50 kg and is moving 2.50 m/s at an angle of 60 degrees above the negative X- axis before the collision. Assume the balls hit squarely without a glancing blow so the balls can roll in the direction calculated normally....
Ball A, of mass 0.6kg, is initially moving to the right at 4 m/s. Ball B, of mass 1.8kg, is initially to the right of ball A and moving to the right at 2 m/s. After the two balls collide, ball B is moving at 3 m/s in the same direction as before. What is the velocity of ball A after this collision. Is this collision elastic or inelastic? What is the fractional change in kinetic energy?

Question 1 10 pts 1) A mass of 4 kg is moving at some velocity and collides inelastically with a 7 kg moving in the-x direction at 10 m/s. After the collision, both masses are moving in the -x direction and the total kinetic energy of both masses is 68 Joules. What was the momentum of the 4 kg mass before collision in kg m/s? Include a negative sign if moving in the negativex direction.
