A particle of m1=0.30 kg slides along the right axis on a frictionless floor with a speed of 2.0 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2=0.40 kg. When particle 2 then reaches a wall at xw = 72 cm, it bounces from the wall with no loss of speed. At what position on the x axis (in cm) does particle 2 collide with particle 1?

A 0.0101-kg bullet is fired straight up at a falling wooden block that has a mass of 4.08 kg. The bullet has a speed of 575 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the colllision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to momentary halt at the top of the building. Find the time t.
A steel ball of mass 0.710 kg is fastened to a cord that is 89.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure.

Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number i Unit (b) Number i Unit
Two blocks of clay, one of mass 1.00 kg and one of mass 6.00 kg, undergo a completely inelastic collision. Before the collision one of the blocks is at rest and the other block is moving with kinetic energy 32.0 J. If the 6.00 kg block is initially at rest and the 1.00 kg block is moving, what is the initial speed of the 1.00 kg block?
