In the figure puck 1 of mass m, = 0.50 kg is sent sliding across a frictionless lab bench, to undergo a one-dimensional elastic collision with stationary puck 2. Puck 2 then slides off the bench and lands a distance d from the base of the bench. Puck 1 rebounds from the collision and slides off the opposite edge of the bench, landing a distance 3.0d from the base of the bench. What is the mass of puck 2? (Hint: Be careful with signs.) 3.0- Number +1 Units

A 0.50-kg bomb is sliding along an icy pond (frictionless surface) with a velocity of 2.0 m/s to the west.  The bomb explodes into two pieces.  After the explosion, a 0.20-kg piece moves south at 4.0 m/s.  What are the components of the velocity of the 0.30-kg piece

Two titanium spheres approach each other head-on with the same speed and collide elastically. After the collision, one of the spheres, whose mass is 480 g, remains at rest. (a) What is the mass of the other sphere? (b) What is the speed of the two-sphere center of mass if the initial speed of each sphere is 4.7 m/s?

On a frictionless horizontal air table, puck A (with mass 0.255 kgkg ) is moving toward puck B (with mass 0.367 kgkg ), which is initially at rest. After the collision, puck A has velocity 0.121 m/sm/s to the left, and puck B has velocity 0.655 m/sm/s to the right. What was the speed vAivAiv_Ai of puck A before the collision? Calculate ΔKΔKDeltaK, the change in the total kinetic energy of the system that occurs during the collision.

A 5.25-g bullet is fired into a 360-g block of wood suspended as a ballistic pendulum. The combined mass swings up to a height of 8.75 cm. What was the magnitude of the momentum of the combined mass immediately after the collision?

An instrument-carrying projectile of mass m1 accidentally explodes at the top of its trajectory. The horizontal distance between launch point and the explosion is x0. The projectile breaks into two pieces that fly apart horizontally. The larger piece, m3, has three times the mass of the smaller piece, m2. To the surprise of the scientist in charge, the smaller piece returns to earth at the launching station. Neglect air resistance and effects due to the earth’s curvature. How far away from the original launching point does the larger piece land

On a horizontal frictionless table, masses A and B (3 kg, 5 kg) slide to the right and left, respectively. They have speeds of 3 m/s and 1 m/s, respectively. The two masses collide, and bounce off each other. After the collision, they travel in opposite directions at speeds of 1.5 m/s and 1.700 m/s, respectively. (Note:In this problem, please use + dir = right, - dir = left, to indicate direction.) a.) Calculate A's momentum: before collision: kg-m/s after collision: kg-m/s Make sure you understand why it is NOT conserved. b.) Calculate B's momentum: before collision: kg-m/s after collision: kg-m/s Make sure you understand why it is NOT conserved. c.) Calculate the A+B system's momentum: before collision: kg-m/s after collision: kg-m/s Make sure you understand why it IS conserved. d.) Calculate the kinetic energy of the A+B system: before collision: after collision: J What kind of collision is this v ---Select--- elastic somewhat inelastic Submit Answer completely inelastic

(ODC-1) Consider two hockey pucks, each with mass 1.25 kg, on frictionless ice. Puck A is initially moving due east at 2.35 m/s towards puck B, which is initially stationary. The pucks. collide head on. After the collision, puck B moves east with a speed of 1.45 m/s. (a) What is puck A's speed (in m/s) after collision? What direction is it moving in? (b) How much kinetic energy (in Joules) is lost from the system during the collision? (c) If the collision were completely elastic, what wold the final speed and direction of each puck be?
