I need to prove to my teacher that i know how to use physics forums, so can i get a response?:smile:

a 2.5 kg ball strikes a wall with a velocity of 8.5 m/s to the left. The ball bounces off with a velocity of 7.5 m/s to the right. If the ball is in contact with the wall for .25s, what is the constant force exerted on the ball by the wall?

If two cars collide going 50 meters/ second head on. Their velocity final was 20 meters per second. For 10 meters. Could i find the momentum?

watters I need help starting it! I'm sort of confused. Thanks for your time.

A 5.5 g bullet is fired into a block of wood with a mass of 22.6g. The wood block is intially at rest on a 1.5m tall post. After the collision, the wood block and bullet land 2.5m from the base of the post. Find the initial speed of the bullet.
