Review Study Momentum/Impulse and Heat!! If a glass of water at 25oC is added to glass of 35oC water what will the new water temperature be? Impulse is equal to the change in ____ If two skaters are standing facing each other and they push away what will the momentum be of each skater? A .06 kg tennis ball moves at a velocity of 12m/s. the ball is struck causing it to rebound in the opposite direction at a speed of 18m/s. What is the balls new momentum? What is conservation of momentum? A 1kg ball traveling 10m/s hits a 2kg ball at rest. After the collision the 1kg ball stops. After the collision what is the resulting velocity of the 2kg ball?
