An air hockey puck is moving with a velocity of 2 in/sec towards a second puck that is at rest. After the two pucks collide, the first puck reverses direction and moves at 0.7 in/sec. If the pucks have the same mass, what is the velocity of the second puck after the collision in m/s? Assume the air hockey table has no friction and that all of the motion is in one dimension

A hockey puck moving at 0.460 m/s collides with another puck that was at rest. The pucks have equal mass. The first puER is deflected 37.0° to the right and moves off at 0.360 m/s. What is the speed of the second puck after the collision? m/s

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 29 m/s. The masses of the two objects are 2.8 and 8.8 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is the one moving initially and the case (b) when the small-mass object is the one moving initially.

A 0.060-kgkg tennis ball, moving with a speed of 5.80 m/sm/s , has a head-on collision with a 0.090-kgkg ball initially moving in the same direction at a speed of 3.48 m/sm/s . Assume that the collision is perfectly elastic. Determine the speed of the 0.090-kgkg ball after the collision. Express your answer to two significant figures and include the appropriate units.

A 92 kg boulder , moving at 5.0 m/s attempts to pass directly across the adit of a mine. Just as the boulder reaches the end of the adit, it was met head-on in midair by two 75 kg miners, both moving in the direction opposite the boulder. One is moving 2.0 m/s, the other at 3.0 m/s . They all become entangled as one mass. What is their velocity after the collision? 18. What is the momentum of a 18 kg object traveling at a constant velocity that has 295 J of kinetic energy?

V ? A hockey puck of mass 4m has been rigged to explode, as part of a practical joke. Initially the puck is at rest on a frictionless ice rink. Then it bursts into three pieces. One chunk, of mass m, slides across the ice at speed v. Another chunk, of mass 2m, slides across the ice at speed 2v, in a direction at right angles to the direction of the first piece. From this information, find the velocity of the final chunk. Initally at rest

Two toy cars with masses of 0.70 kg  and 0.30 kg, respectively, move towards each other and collide  head-on and then stick together.. The magnitude of the initial velocity for each of of the toy cars is 15.0 m/s. What is the speed of the toy cars  immediately after collision?

A 9.7-g bullet is fired into a stationary block of wood having mass m = 5.10 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.606 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)

A fast car is speeding down a road with a velocity of v. It collides with a truck moving in the opposite direction that has a mass that is four times that of the fast car. They are both moving at the same speed. If the collision is elastic, then what are both of the vehicles velocities given as multiples of v.

Block A, with a mass of 0.410 kg, is traveling north on a frictionless surface with a speed of 5.00 m/s. Block B, with a mass of 0.480 kg, travels west on the same surface until it collides with A. After the collision, the blocks move off together with a velocity of 3.13 m/s at an angle of 42.5° to the north of west. What was B’s speed just before the collision?
