Q1. Two balls are hung from the cords. The first ball, of mass 1.5 kg, is pulled to the side and discharged, reaching a speed of 2.1 m/s at the bottom of its arc. Then, it hits and sticks to the other ball. The speed of the pair just after the collision is 1.5 m/s.

Determine the mass of second ball?

Q2. A block slides down a smooth ramp, beginning from rest at a height h. When it reaches the bottom it’s moving at speed Vi. It then persists to slide up the second smooth ramp.

At what height is its speed equivalent to Vi/2?

Q3. On a frictionless horizontal air table, puck A (with mass 0.255 kg ) is moving toward the puck B (with mass 0.369 kg ), that is initially at rest. After the collision, puck A has a velocity of 0.118 m/s to the left, and puck B has a velocity of 0.651 m/s to the right.

a) Determine the speed of puck A before the collision?

b) Compute Δk, the change in the total kinetic energy of the system which takes place during the collision.
