A curling stone, with a mass of 20.0 kg, slides across the ice at 1.50 m/s. It collides head on with a stationary 0.160-kg hockey puck. After the collision, the puck’s speed is 2.50 m/s. What is the stone’s final velocity?
Added by Kacia G.
Step 1
The total momentum before the collision is equal to the total momentum after the collision. The initial momentum of the system is the momentum of the curling stone, because the hockey puck is stationary and therefore has no momentum. The momentum of an object is Show more…

A curling stone A (mA = 25 kg) is moving at 3.0 m/s [E] down the centre line of the ice toward an opponent's stone B (mB = 15 kg), initially at rest. Immediately after this collision, stone A continues moving with a velocity of 1.8 m/s [E 22º N]. What is the velocity of stone B after the collision?

A curling stone of mass 20 kg and initially traveling at 2.0 m/s collides head-on with a lighter stone of mass 15 kg which is initially at rest. After the collision the struck stone has a speed of 1.6 m/s in the same direction as the initial velocity of the heavy stone. a) What is the final velocity of the heavy stone? b) Is this collision elastic? Explain. If the collision is not elastic, find the macroscopic energy lost in the collision
