Two balls of equal mass undergo a collision. Ball 1 is initially travelling horizontally with a speed of 10 m/s, and ball 2 is initially at rest. After the collision, ball 1 moves away with a velocity of 4.7 m/s at an angle of ? = 60 degrees from its original path and ball 2 moves away at an unknown angle ∅. Determine the magnitude and direction of velocity of ball 2 after the collision.

Question A puck with mass ma= 0.00242 kg moves eastward with speed  va= 1.73 m/s . It then collides with another puck of mass mb= 0.00125 kg and is moving northward with a speed vb = 2.26 m/s After the collision, puck A now moves at 48. 0° north of east, while puck B moves at 17.0° south of east.   A. What are the speeds of the two pucks after collision?

V₁ = 7 m/s V₂ = 5 m/s m₁ = 2 kg m₂ = 3 kg

Two objects, A and B, with masses 3.2 kg and 1.8 kg, move in a frictionless horizontal surface. Object A moves to the right at a constant speed of 5.1 m/s while object B moves to the right at a constant speed of 1.4 m/s.  They collide and stick together. a) Find the total kinetic energy of the system after the collision. b) Is the kinetic energy of the system conserved?  Explain.

Block A of mass m = 1.48 kg moving on a horizontal plane with velocity of vj = 1.71 m/s collides with Block B of the same mass at rest before the collision. After the collision, Block A stops. What is the velocity of Block B Vf after collision? Assume there is no friction between the blocks and the horizontal plane. Keep three significant figures for the answer.

A bullet of mass m = 8.00 g is fired into a block of mass M = 220 g that is initially at rest at the edge of a table of height h = 1.00 m (see figure below). The bullet remains in the block, and after the impact the block lands d = 1.60 m from the bottom of the table. Determine the initial speed of the bullet. __ m/s

Two cars each with a speed of 30 m/s are sliding on frictionless ice at an intersection and collide. Car #1 has mass 1400 kg and Car#2 has mass 1300 kg. The cars stick together after colliding. A) What is the angle the combined mass comes off the collision at ? B)What is the speed of the combined mass?

Lucy is cruising through space in her new spaceship. As she coasts along, a tiny spacebug drifts into her path and bounces off the window. Consider several statements concerning this scenario. Evaluate each statement according to the law of momentum conservation and match it to the appropriate category. Must be true according to the law of momentum conservation Must be false according to the law of momentum conservation Answer Bank Not determined by the law of momentum conservation If the spacebug had stuck to the spaceship instead of bouncing off, momentum would not have been conserved for this interaction. The change in the spacebug's momentum during the collision is greater than the change in the spaceship's momentum. The total chanaa in momentum for this interaction is nem The total momentum of the spaceship and spacebug before the collision is equal to their total momentum afterward. 日示全部 X

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.
