The figure below shows a bullet of mass 200 g traveling horizontally towards the east with speed 400 m/s, which strikes a block of mass 1.5 kg that is initially at rest on a frictionless table.  After striking the block, the bullet is embedded in the block and the block and the bullet move together as one unit.    A. What is the magnitude and direction of the velocity of the block/bullet combination immediately after the impact?   B. What is the magnitude and direction of the impulse by the block on the bullet?   C. What is the magnitude and direction of the impulse from the bullet on the block?   D. If it took 3 ms for the bullet to change the speed from 400 m/s to the final speed after impact, what is the average force between the block and the bullet during this time?

Calculate the average acceleration of the shell in the tube as it goes from zero to the velocity found in (a). (c) What is the average force on the shell in the mortar? Express your answer in newtons and as a ratio to the weight of the shell.
