10. A 2.0 kg ball moving with a speed of 3.0 m/s hits, elastically, an identical stationary ball as shown. If the first ball moves away with angle 30 Degree to the original path, determine a. the speed of the first ball after the collision. b. the speed and direction of the second ball after the collision.
5. Ball 1 has a mass of 2.0 kg and is suspended with a 3.0 m rope from a post so that the ball is stationary. Ball 2 has a mass of 4.0 kg and is tied to another rope. The second rope also measures 3.0 m but is held at a 60.0° angle, as shown in Figure 7. When ball 2 is released, it collides, head-on, with ball I in an elastic collision. (a) Calculate the speed of each...
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...
A 6 kg bowling ball rolling at 5 m/s strikes a stationary 4 kg bowling ball. If ball #1 is moving forward at 2 m/s after the collision, what is the speed and direction of ball #2? What is the impulse of the system? If the collision last for .5 seconds, how much force is exerted?
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...
6.51 in text book] A billiard ball moving at 5.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 4.33 m/s at an angle of 30◦ with respect to the original line of motion. a) Find the velocity (magnitude and direction) of the second ball after the collision[vx2f = 1.25 m/s and vy2f = −2.165m/s]. b) Was the collision inelastic or elastic?

After the collision , one ball is found to be moving at a speed of 4m/s in a direction 60 degree above the horizontal . Find the velocity of the other ball in polar form ? Is the collision elastic or inelastic?
In the game of billiards, all the balls have approximately the same mass, about 0.17 kg. In the figure, the cue ball strikes another ball that is at rest, such that it follows the path shown. The other ball has a speed of 1.5 m/s immediately after the collision. a.) What is the kinetic energy of the cue ball after the collision? b.) Is the collision elastic or inelastic? 3.0 m/s 30.0° O 60.0° 1.5 m/s
