Two billiard balls with identical masses of 1 kg move toward each other. The initial velocity of ball 1 is +30 cm/s and...
Let the red cart have a mass of 1 kg and an initial velocity of +10 m/s, and the blue cart have a mass of 3 kg and an initial velocity of -10 m/s. If the two carts experience an Elastic Collision, what will be the final velocity of the blue cart? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer units Question 5 (0.2 points) In which type of collision is...
Two balls, of masses m and 2m, travelling in a vacuum with initial velocities 2v and v respectively, collide with each other head-on, as shown. m 2v v 2m After the collision, the ball of mass m rebounds to the left with velocity v.

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?
Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are v1i = +25.2 cm/s and v2i = ?20.1 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.) v1f = cm/s...

8. (9 pts.) A 4.00-kg ball, moving to the right at a velocity of +2.00 mis on a frictionless table, collides head-on with a stationary 6.50-kg ball. Find the final velocities of the balls if the collision is completely inelastic (the balls stick together). 9. (12 pts.) A 2.5-kg ball and a 5.0-kg ball have an elastic collision. Before the collision, the 2.5-kg ball was at rest and the other ball had a speed of 3.5 m/s. (a) What is...
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
Ball 1, with a mass of 114 g and traveling at 11.6 m/s , collides head on with ball 2, which has a mass of 319 g and is initially at rest. Assume that ball 1 is traveling to the right before the collision and that the collision is one dimensional.(2 questions thank you) What is the final velocity of ball 1 if the collision is perfectly elastic? What is the final velocity of ball 2 if the collision is...
PRACTICE IT . Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure.
