On a frictionless, horizontal air table, puck A (with mass 0.250 kg) is moving toward puck B (with mass 0.350 kg), which is initially at rest. After the collision, puck A has a velocity of 0.120 m/s to the left, and puck B has a velocity of 0.640 m/s to the right. a)What was the speed of puck A before the collision? b)Calculate the change in the total kinetic energy of the system that occurs during the collision.

Two spheres, each of mass m, can slide freely on a frictionless, horizontal surface. Sphere A is moving at a speed v0 = 16 ft/s when it strikes sphere B which is at rest, and the impact causes sphere B to break into two pieces, each of mass m/2.a) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the velocity of sphere A after the collision.b) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the angle θ and the speeds of the two pieces after the collision.

A 5000.0-kg truck moving rightward with a speed of 5.00 km/hr collides head-on with a 1000.0-kg car moving leftward with a speed of 20.0 km/hr. The two vehicles stick together and move with the same velocity after the collision. Determine the post- collision velocity of the car and truck. Final velocity = km/hr %3D

1.) A car (mass=400 kg) is traveling down a country road (speed is 10 m/s) when it collides with a deer (mass=200 kg) which is running in the opposite direction (speed is 2 m/s). The collision results in the deer getting stuck on the windshield. Treat this collision using the 'conservation of momentum' principle: a) Draw a sketch - label each MASS and each VELOCITY (with arrows for direction). b) Calculate the final speed of the car (remember the deer is stuck on top of the car) after collision (Note: they stick together to form a single mass)

The following figure shows two particles of masses m1 and m2, with velocities before the collision of magnitude v1 and v2. If the collision is perfectly elastic, find the magnitude of the velocities v1' and v2' after the collision and the angle of incidence θ (theta), as a function of the masses and velocities before the collision.
