MOMENTUM Answer what are asked for in the following problems. Show complete solutions. Only the final answers shall be rounded off to two decimal places. 5 points is credited to each correct answer. Otherwise, 2 points shall be given for the effort...(30 points)... 1. Object A is 15.0-kg and was moving at a velocity of 30.0 m/s to the left and collided with object B which has a mass of 30.0-kg and was moving to the right at a velocity of 15.0 m/s. After the collision, object A moved to the right at a velocity of 15.0 m/s. At what velocity did object B move and to what direction? 2. A 0.35-kg ball was at rest before it was hit by a 0.40-kg ball at a velocity of 5.0 m/s to the left. After the collision, both balls were stuck together. At what velocity did they move and to what direction? 3. A 100-g marble was moving to the right at a velocity of 5.0 m/s and collided with a 30.0-g marble moving in the opposite direction at a velocity 3.0 m/s. If the heavier marble stopped moving after the collision, at what velocity did the other marble move and to what direction? 4. After a collision with a 0.70-kg object moving to the right at 3.0 m/s, a 0.20-kg object moving in the same direction at a velocity of 2.0 m/s slowed down at 1.0 m/s. a) What is the velocity of the other object after the collision and to what direction did it move? b) Illustrate the positions of the objects before and after the collision. Label appropriately (use m1 and v1 for the first object and m2 and v2 for the second). 5. A boy drops a 0.500-kg rubber ball on a flat concrete surface from a height of 0.95 m. If the ball bounces at a height of 0.30 m, find its CR.
