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 m/s direction (b) What are the magnitude (in N⋅s) and direction of the impulse by the block on the bullet? magnitude N⋅s direction (c) What are the magnitude (in N⋅s) and direction of the impulse from the bullet on the block? magnitude N⋅s direction N
