Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 5.30 m/s and scatters at an angle of 30° with respect to its incoming direction. What is the velocity (magnitude in m/s and direction in degrees counterclockwise from the +x-axis) of puck 1 after the collision? (Assume the +x-axis is to the right.) 30° magnitude direction 2.65 m/s 45 X ° counterclockwise from the +x-axis

You're playing pool and you line up a shot on the 3 ball. You want the 3 ball to be deflected by an angle o3=25 degrees at a velocity v3=1.3 m/s so that it will make it into a side pocket. What initial velocity must you give the cue ball in order to make this shot and what will be the velocity and angle of the cue ball following the collision? Recall that the mass of a cue ball is 0.17 kg and the mass of a 3 ball is 0.16 kg.

Air hockey is a game played on a table. A puck (shown in black) slides freely on a cushion of air. Opposing players strike the puck with a hand-held round "paddle" (shown in red). In one case, while playing air hockey, the puck comes toward you with a speed of 0.8 m/s at an angle of 30° above the -x axis in the xz plane. You strike it with your paddle, and after the collision, the puck travels in the +x direction with a speed of 2.9 m/s toward the opponent's goal. The mass of the puck is 0.020 kg.

A ball struck by a bat experiences a change in momentum of 42 kg m/s . If the time of interaction is 0.29 s, what is the magnitude of the average force acting on the ball (in N) ?

A truck (M = 2500kg) collides with a car (m = 1000kg) at a 4-way intersection. Fortunately nobody gets hurt. Suppose the car is going north at 20m/s ( about 45mph) and the truck is coming from the east at 10m/s ( about 22mph). The car and truck stick together after the %3D collision. (a) Find the speed and direction of the car and truck immediately after the collision. (b) Approximately how much energy went into the deformation of the metal that caused the two vehicles to stick together? (c) What assumptions did you make? The

A hockey puck with a mass of 0.170 kg moving in a straight line at 1.7 m / s collides with an identical puck that is at rest. As a result, the first disk deviates an angle of 30 ° from its original path and continues to move with a speed of 0.45 m / s. What is the angle of the final velocity of the second disk?

A white billiard ball, moving horizontally strikes the number 2 billiard ball, at rest. Before impact, the white ball was moving at a speed of 3.50 m/s and angle of 23° from the horizontal, and after impact it is moving at 0.75 m/s at 47° from the horizontal. a. If the two balls have equal masses of 140 g, what is the velocity of the red ball after the impact? Include its magnitude and direction.

Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 7.24 m/s and scatters at an angle of 30° with respect to its incoming direction. What is the velocity (magnitude in m/s and direction in degrees counterclockwise from the +x-axis) of puck 1 after the collision? (Assume the +x-axis is to the right.) 30° magnitude m/s direction o counterclockwise from the +x-axis

On a frictionless horizontal air table, puck A (with mass 0.255 kgkg ) is moving toward puck B (with mass 0.367 kgkg ), which is initially at rest. After the collision, puck A has velocity 0.121 m/sm/s to the left, and puck B has velocity 0.655 m/sm/s to the right. What was the speed vAivAiv_Ai of puck A before the collision? Calculate ΔKΔKDeltaK, the change in the total kinetic energy of the system that occurs during the collision.

A baseball with a mass of 0.15 kg is batted into the air. It's initial speed is 35.8 m/s directed at an angle 28 degrees above the horizontal. After 0.19 seconds what is the horizontal component of the balls velocity in m/s?
