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). Problem: A 4.00-g bullet moves horizontally with velocity of + 355m / s. The mass of the first block is 1150 g, and its velocity after the bullet passes through it it is +0.550 m / s. The mass of the second block is 1530 g. (a) Obtain the speed of the bullet after passing through the first block, (b) obtain the velocity of the second block after the bullet is buried in it

A0.014-kg bullet is fired intoa stationary block of wood of mass of 4.51 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded in the block of wood). What is the speed of the bullet-plus-wood combination immediately after collision if the speed of the bullet before collision is 476 m/s? Express yourlanswer in two decimal places and with units of m/s.

Consider the two pucks shown in the figure. As they move towards each other, the momentum of each puck is equal in magnitude and opposite in direction. Given that v; oreen = 12.0 m/s, and mblue is 25.0% greater than mareen, what are the final speeds of each puck (in m/s), if - the kinetic energy of the system is converted to internal energy? 30.0 30.0 Vgreen m/s V blue m/s

Problem 7.01. A 2.5 kg Hellbender (a.k.a. lasagna lizard, the official amphibian of PA) swims with a speed of 5.0 m/s down a stream which flows at 10.0 m/s. a) How much momentum does the Hellbender have with respect to still water? b) How much momentum does the Hellbender have with respect to the Earth?

A 120 kg man is standing in the middle of a skating rink holding a 2kg ball. He suddenly throws the ball eastward at 5 m/s. What is the magnitude of his momentum afterward? Assuming frictonless between his skateboots and the ice.
