Bullet vs Block. A block of mass M rests on a flat horizontal surface. A hole is cut in the surface underneath the centre of the block. A bullet of mass m is then fired directly upward at the block from below and strikes the underside of the block with speed u.

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vo = 5.60 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 0 = 38.0° with the horizontal axis while the green disk makes an angle of q = 52.0° with this axis as in Figure b. Determine the speed of each disk after the collision. Vof= m/s |m/s After the collision Before the collision -x

Rockets are not always launched straight up. Consider a rocket launcher consisting of a ramp inclined at 30 degrees above the horizontal. The mass of the rocket is 4,000 kg of which 3,000 kg is fuel. The exhaust speed is 1,000 m/s and the fuel is burned at a constant rate of 200 kg/s. You may assume a flat, airless, nonrotating Earth. a) Determine the velocity and direction of the rocket at the time all the fuel is burned. b) Determine its position at this time.
Suppose you have two pucks on flat ice. Puck A has mass 0.150kg and puck B has mass 0.110kg. The coefficient of kinetic friction on the ice for pucks is 0.040. Puck B is initially at rest. Puck A hits puck B head-on (don't assume elastic though). If after the collision puck A slides 18m and puck B slides 30m, what was puck A's initial velocity right before the collision?
A 6.71-g bullet is moving horizontally with a velocity of +362 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1158 g, and its velocity is +0.550 m/s after the bullet passes through it. The mass of the second block is 1535 g. (a) What is the velocity of the second block after the bullet imbeds itself?

Quesitos: The drawing shows a bullet passing through two blocks that rest on a horizontal, frictionless surface. Rule out air resistance. The bullet completely passes through the first block and is buried in the second block. Notice that after the collision, both blocks move. Can the Conservation Principle be applied from Linear Momentum to this three-body system? Justify your answer (Ignore any loss of mass from the first block).
