A 2.00-kg object hangs, at rest, on a 1.00-m-long string attached to the ceiling. A 100-g mass is fired with a speed of 20 m/s at the 2.00-kg mass, and the 100.00-g mass collides perfectly elastically with the 2.00-kg mass. Write an equation for the motion of the hanging mass after the collision. Assume air resistance is negligible.

A spring with relaxed length 0.30 m and spring constant 1.8 N/m rests horizontally on a frictionless table and is anchored frmly to a wall on one side. You press a 400 g block into the other side until the spring length is 0.16 m and then let go. a.) What will the momentum of the block be when it departs from the spring? (Assume contact ceases when the spring is relaxed.) b.) If the table were no longer frictionless and the block-table interface had a kinetic coeffcient of friction of 0.1 what then would the momentum of the block be when it departs from the spring?
