15. + 1/3 points Previous Answers Tipler6 8.P.087.soln. My Notes + Ask Your Teacher A puck of mass 0.30 kg approaches a second, identical puck that is stationary on frictionless ice. The initial speed of the moving puck is 3.0 m/s. After the collision, one puck leaves with a speed v1 at 30° to the original line of motion. The second puck leaves with speed v2 at 60°. 130° 600 (a) Calculate V1 and v2. V1 = m/s V2 =...
A puck with a mass m1 = 50.0 g moving at 1.00 m/s approaches a stationary puck with a mass m2 = 100 g on an air table and they undergo a two-dimensional elastic collision. After the collision, both pucks have identical speeds, but travel in di?erent directions. What is the angle between the original and ?nal paths of m1?
On a frictionless tabletop, a sphere of mass 3.0 kg and speed 18 m/s approaches head on and collides elastically with a stationary sphere of mass 5.0 kg. Find out he velocity of the first sphere after the elastic head on collision. 4.5 m/s 0 - 4.0 m/s 0 - 4.5 m/s O 40 m/s
Please explain the answer... 58) A puck with a mass m1 50 g moving at 1.0 m/s approaches a stationary puck with a mass m2 100 g on a frictionless air table, and they undergo a sudden two-dimensional elastic collision.

A hockey puck of mass 0.16 kg, sliding on a nearly frictionless surface of ice with a velocity of 2.0 m/s [E], strikes a second puck at rest with a mass of 0.17 kg. The first puck has a velocity of 1.5 m/s [N 31o E] after the collision. Determine the velocity of the second puck after the collision. TA 6.
(20 pts) On a frictionless, horizontal air table, puck A (with mass 0.15 kg) is moving toward puck B (with mass 0.3 kg), which is initially at rest. After the collision, puck A has a velocity of 0.11 m/s to the left, and puck B has a velocity of 0.65 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 (A and B)...
20. A hockey puck travels across the ice at a speed of 38 m/s 34° north of east. It has a glancing collision with a stationary puck of the exact same mass. The previously stationary puck moves at 33 m/s 24° north of east. What is the speed and direction of the first puck (both pucks have a mass of 0.3 kg) after the collision? Is the collision elastic or inelastic?
A hockey puck B rests on frictionless, level ice and is struck by a second puck A, which was originally traveling at 40.0 m/s and which is deflected 30 degrees from its original direction. Puck B acquires a velocity at a -45 degree angle to the original direction of A. The pucks have the same mass. a) compute the speed of each puck after the collision b) what fraction of the original kinetic energy of puck A dissipates during the...
