The figure below shows a bullet of mass 210 g traveling horizontally towards the east with speed 410 m/s, which strikes a block of mass 5.5 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 are the magnitude (in m/s) and direction of the velocity of the block/bullet combination Immediately after the impact? magnitude x m/s direction -Select- v x (b) What are the magnitude (in N . s) and direction of the impulse by the block on the bullet? magnitude N . S direction -Select- (c) What are the magnitude (in N . s) and direction of the impulse from the bullet on the block? magnitude N . S direction -Select- (d) If it took 3 ms for the bullet to change the speed from 410 m/s to the final speed after Impact, what is the average force (in N) between the block and the bullet during this time? (Enter the magnitude.) IN
