A Nerf dart (mass=0.001 kg) is fired into a box (mass=0.035 kg) that is hanging from a string, and the dart remains in the box after the collision. a) What kind of collision is this? How do you know? b) The box is initially at rest, but it swings to a height of 0.10 m after the collision. What velocity did the box have after the collision? c) What velocity did the dart have before the collision?

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

A 2.10-kg block is moving to the right at 1.20 m/s just before it strikes and sticks to a 1.00-kg block initially at rest. What is the total momentum of the two blocks after the collision? Enter a positive answer if the total momentum is toward right and a negative answer if the total momentum is toward left.
Two toy cars have a collision and bounce off each other. The first has a mass of 0.5 kg and was initially traveling at 3.5 m/s. The second has a mass of 0.8 kg and had an initial velocity of -2.0 m/s. After colliding the first recoils with a velocity of v1f = -1.19 m/s. After colliding, what is the velocity of the second car? 3.5 m/s -2.0 m/s m=0.5kg m=0.8 kg m-0.5kg m-0.8 kg V=? m=0.5kg m=0.8 kg
