Please show your solutions neatly in paper.I will give you a very good feedback. Thank you!

1. A 60 gm mass with a horizontal velocity of 50 cm, collides with an 85 g mass at rest. After collision, the 60 g mass travel 30 below the horizontal and the 85 g mass travels 450 above the horizontal. Find the speed of each mass after impact. 2. A 3 kg block moving to the right on a frictionless table at 4 " |makes a head on collision with another 3 kg block moving 5 ~ , to the left. a) If the collision is completely inelastic, find the final velocity of the blocks. b) If the collision is completely elastic, find the final velocity of the blocks. If half the initial energy is dissipated in the collision, find the final velocities of the blocks
