Find the speed of the bullet after it has passed through a block.

A 3gm bullet with a speed of 300m/sec is fired on a 400gm block initially at rest. The bullet passes through the block and as a result the block begins to move with a speed of 1.5m/sec in the original direction of the bullet. Find the speed of the bullet after it has passed through the block.

Velocity, conservation of momentum, force, force of gravity

1. A ball is thrown in the air with enough force so that it goes straight up for several seconds. a. What is the velocity of the ball 1 sec before it's highest point? b. What is the change in velocity during this 1 sec interval? c. What is the velocity 1 sec after it reaches it's highest point? d. what is the change in veloc
