A hockey puck moving at 0.460 m/s collides with another puck that was at rest. The pucks have equal mass. The first puck is deflected 37.0° to the right and moves off at 0.380 m/s. What is the speed of the second puck after the collision?

A railroad car of mass 3.50 ✕ 104 kg moving at 3.05 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. a) What is the speed of the three coupled cars after the collision?  b) How much kinetic energy is lost in the collision?

The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.0190 kg and is moving along the x axis with a velocity of +4.08 m/s. It makes a collision with puck B, which has a mass of 0.0380 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a) puck A and (b) puck B. (a) Number (b) Number At rest B 65 A 37 B Before collision After collision Units Units

A railroad car of mass 2.55 × 104 kg moving at 2.85 m/s collides and couples with two coupled railroad cars, each of the sam mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? 1.75 m/s (b) How much kinetic energy is lost in the collision?

Object A traveling east at 8.47 m/s collides with object B traveling west at 2.43 m/s. Object A has mass 2.82 kg and object B has mass 8.24 kg. The collsion takes place in one dimension, and is totally inelastic. Taking east to be positive, find the velocity of object A (in m/s) after the collision.

Shown is a collision between two pucks on an air hockey table. Puck a has mass 0.025kg and is moving along the x-axis with a velocity of +5.5m/s. It makes a collision with puck B, which has a mass of 0.05kg and is initially at rest. The collision is not head-on. After the collision the pucks fly off with the angles as shown. +5.5 m/s At rest Before collision 65 37- After collision What is the speed of puck A? (4) m/s What is the speed of puck B? (4) m/s

A billiard ball moving at +10.0 m/s along the x-axis collides with a second billiard ball, of identical mass, at rest.  After the collision, the first (incoming) ball moves off with a velocity of 7.7 m/s at an angle of 40 degrees above the x-axis.  What is the velocity of the second ball after the collision?

What is the final speed of object two in m/s?

A 65.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped at him at a velocity of 28.0 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities (in m/s) be in this case? (Assume the original direction of the ice puck toward the goalie is in the positive direction. Indicate the direction with the sign of your answer.) puck m/s goalie m/s
