A wooden block is cut into two pieces, piece A with six times the mass of the other piece, B. A depression is made in both faces of the cut, so that a firecracker can be placed in it with the block Part A reassembled. The reassembled block is set on a rough-surfaced table, and the fuse is lit. When the firecracker explodes inside, the two blocks separate and slide apart. What is the ratio of the magnitudes of the distances each block travels? Express your answer using three significant figures. ? |(Ax)al |(A=)B| %3D

Blocks A and B are moving toward each other on a horizontal, frictionless surface. Block A has a mass of 5 kg and a velocity of +40 m/s, while B has a mass of 10 kg and a velocity of -6 m/s. They suffer a head on, completely inelastic collision. What is the common speed of the blocks after the collision.

A block of mass mm = 16 kgkg has a speed VV and is behind a block of mass MM = 65 kgkg that has a speed of 0.5 m/sm/s. The surface is frictionless. The blocks collide and couple. After the collision, the blocks have a common speed of 0.9 m/sm/s. In the figure, the loss of kinetic energy of the blocks due to the collision is closest to: 7.7 J 25 J 26 J 9.3 J 76 J

INITIAL: FINAL: M. A white billiard ball with mass mw = 1.53 kg is moving directly to the right with a speed of v = 3.25 m/s and collides elastically with a black billiard ball with the same mass mb = 1.53 kg that is initially at rest. The two collide elastically and the white ball ends up moving at an angle above the horizontal of ew = 51° and the black ball ends up moving at an angle below the horizontal of Ob = 39°. %3D 1) What is the final speed of the white ball? m/s Submit 2) What is the final speed of the black ball? m/s Submit
