A 10 kg ball A moving horizontally at 12 m/s collides with a 10 kg block B. The coefficient of restitution of the impact is 0.4 and the coefficient of kinetic friction between the block and the inclined surface is 0.5. Calculate the impulse made by the impulsive normal that produces the impact, the speed of the two bodies A and B after the impact and the distance that the block rises and how long it takes to stop.
![A 12.0−g wad of sticky clay is hurled horizontally at a 100−g wooden block initially at rest on a horizontal surface. The clay sticks to the block. After impact, the block slides 7.50 m before coming to rest. If the coefficient of kinetic friction between the block and the surface is 0.650 , what was the speed of the clay immediately before impact? (5 - Appl) 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 [E22∘N]. What is the velocity of stone B after the collision?
