Let a mass of 3.0 kg be standing still and a secondmass of 5.0 kg come along and hit it with velocity 4.0 m/s. Supposethe smaller mass moves off with a speed of 5.0 m/s.a) Draw a diagram to describe the situation before the collision.b) What is the velocity of the 5.0 Kg mass after the collision?c) Draw a diagram to describe the situation after the collision.d) What type of collision is it? Support your answer with calculations from Lawof Conservation of Momentum, and Law of Conservation of Energy.

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?

1) A 100 g cart initially moving at +0.5 m/s collides elastically from a stationary 180 g cart. a) Using the equation in the theory, calculate the final velocity of the 100 g cart. b) Calculate the change in the momentum of the 100 g cart. c) Since this is an elastic collision, total momentum must be conserved. Using your answer for part b, calculate the final velocity of the 150 g cart.

0.070 kg weighted mass by the clay ball was shot upwards, traveling 1.0 m before hitting and sticking to a brick of mass 2.0 kg suspended from the ceiling by a light cord. As a result of the collision, the brick + clay ball rises through a distance of 10.0 cm. Find the answers to the questions, part a and b. a) What was the speend of the ball of clay when it struck the brick? b) What was the speed of the launch by the clay ball?

Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 3.0 x 104 kg (about 30 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of N for 20 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis. Also think about the choice of system: what are the surroundings that exert external forces on your system?)
