1.Two shuffle board disks of equal mass, one orange and the other yellow are involved in an elastic, glancing collision. The yellow disk is initially at rest and is struck by the orange disk moving with a speed of 4m/s. After the collision, the orange disk moves along a direction that makes an angle of 73° with its initial direction motion. The velocities of the two disks are perpendicular after the collision. Determine the final speed of each disk.

1. In an experiment, you throw a rubber ball of mass m = 25.0 g onto a block of mass M = 250 g that is initially at rest at the edge of a table of height h = 0.98 m. (Figure) The ball bounces back with a speed of 1.01 m/s, and the block eventually lands at d = 1.02 m from the bottom of the table. What is the speed of the ball, right before it hits the block?

A child sleds down a hill and collides at 5.6 m/s into a stationary sled that is identical to his. The child is launched forward at the same speed, leaving behind the two sleds that lock together and slide forward more slowly. What is the speed of the two sleds after this collision?

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.70 m/s, and bumper car 2 is traveling 79.1° south of west at 4.25 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground. W-OE Car 2 Car 1 Vii (a) If the masses of bumper cars 1 and 2 are 596 kg and 625 kg respectively, what is the velocity of the bumper cars immediately after the collision? magnitude m/s direction ° east of south (b) What is the kinetic energy lost in the collision?

m2 m h=7.0m ☐ Figure 1: Diagram for Problem 15 15) During a test investigation, a 40-gram bullet is fired towards a stationary block of 1.0-kg mass causing a perfectly in-elastic collision. After the collision, the block-bullet system slides up a smooth ramp, eventually coming to rest at an elevation of 7.0 meters. Calculate the speed of the bullet. Must show all steps including the equations being used.

Two bumper cars at the county fair are sliding toward one another (see figure below). Initially, bumper car 1 is traveling to the east at 5.90 m/s, and bumper car 2 is traveling 79.0° south of west at 4.15 m/s. They collide and stick together, as the driver of one car reaches out and grabs hold of the other driver. The two bumper cars move off together after the collision, and friction is negligible between the cars and the ground.

A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision.   a)what are is the magnitude of the velocity of the two vehicles just after the collision?

1. A firecracker travels straight up at 75.0m/s and explodes into two pieces. The smaller piece carries one third of the firecracker's mass and shoots off horizontally at 48.0m/s west. Determine the speed and direction of the other piece directly after the explosion. 2. Three blocks slide on a smooth surface. Initially, the first block (m1=1.0kg) moves at 3.0m/s to the right, the second block (m2=2.0kg) is at rest, and the third block (m3=3.0kg) moves to the left at 0.50m/s. First, m1 collides elastically with m2 and recoils to the left. Afterwards, m2 and m3 collide and stick. Calculate, a. the velocities of m1 and m2 after the first collision. b. the velocity of m2 and m3 after the second collision.

云 HI 5 F. %24 -10 Part A Jeanette is playing in a 9-ball pool tournament. She will win if she sinks the 9-ball from the final rack, so she needs to line up her shot precisely. Both the cue ball and the 9-ball have mass m, and the cue ball is hit at an initial speed of v. Jeanette carefully hits the cue ball into the 9-ball off center, so that when the balls collide, they move away from each other at the same angle 0 from the direction in which the cue ball was originally traveling (see figure). Furthermore, after the collision, the cue ball moves away at speed vf, while the 9-ball moves at speed vp. (Figure 1) Find the angle 0 that the 9-ball travels away from the horizontal, as shown in the figure. Express your answer in degrees to three significant figures. > View Available Hint(s) For the purposes of this problem, assume that the collision is perfectly elastic, neglect friction, and ignore the spinning of the balls.
