Two billiard balls of equal mass move at right angles and meet at the origin of an xy coordinate system. Initially ball A is moving upward along the y axis at 2.0m/sm/s, and ball B is moving to the right along the x axis with speed 3.7m/sm/s. After the collision (assumed elastic), the second ball is moving along the positive y axis. What is the final direction of ball A? Express your answer using two significant figures.
On a frictionless air track, a blue glider with a mass 0.200kg is moving to the right with a speed if 8.00m/s. It strikes a red glider that has a mass 0.600kg and that is initially at rest. After the collision, the blue glider is moving to the left with a speed of 2.40m/s. a) what are the magnitude and direction of the velocity of the red glider after the collision?
Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at voi = 3.00 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 35.0° with the horizontal axis while the green disk makes an angle of o 55.0° with this axis as in Figure b.

A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 5.39 m/s at an angle of 26.0° with respect to the original line of motion. Assuming an elastic collision (and ignoring friction and rotational motion), find the struck ball's velocity after the collision. magnitude m/s direction * (with respect to the original line of motion)
A ball of mass 2.00-kg is traveling in the positive x-direction at 10.0 m/s and obliquely collides with a 3.00-kg ball that was initially at rest. After the collision, the 2.00-kg ball is traveling at 30.0° above the positive x-axis, while the 3.00-kg ball has a speed of 4.00 m/s. Determine the direction the 3.00-kg ball is moving relative to the positive x direction, and the speed of the 2.00-kg ball.

Carry Collision Insurance! A 1,906 kg car stopped at a traffic light is struck from the rear by a 953-kg car. The two cars become entangled, moving along the same path as that of the originally moving car. If the smaller car were moving at 26.7 m/s before the collision, what is the velocity of the entangled cars after the collision? (Assume the smaller car initially moves in the positive direction.) SOLUTION Conceptualize This kind of collision is easily visualized, and one can predict that after the collision both cars will be moving in the same direction as that of the initially moving car. Because the initially moving car has only half the mass of the stationary car, we expect the final velocity of the cars to be relatively ---Select--- Categorize We identify the two cars as an isolated system in terms of momentum in the horizontal direction and apply the impulse approximation during the short time interval of the collision. The phrase "become entangled" tells us to categorize the…
Two cars approach an ice-covered intersection. One car, of mass 1.10 103 kg, is initially traveling north at 10.1 m/s. The other car, of mass 1.55 103 kg, is initially traveling east at 10.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Magnitude:
