Conservation of Momentum Practice Problems 1. Two grocery carts collide, a full one with a mass of 35 kg moving East at 2.0 m/s and an empty one with a mass of 10.0 kg moving West at 3.0 m/s. After the collision the full cart is moving East at 0.75 m/s. What is the velocity of the empty cart? M1 = 35 kg MI = V , = 2.0m/s V 3 = mz = mz = VA : 2. Two cans of SPAM with identical masses of 1.0 kg collide. Before the collision, the hickory-smoke flavor was moving to the left at 4.0 m/s, while the hot-and-spicy flavor was moving to the right at 2.0 m/s. After the collision, the hickory-smoke is moving to the left at 1.2 m/s. What is the velocity of the hot-and-spicy? 3. Two barges have a collision. The red barge has a mass of 150 000 kg and is traveling Northwest at 0.25 m/s. The blue barge has a mass of 100 000 kg and is traveling Southeast at 0.1 m/s. After the collision the blue barge has a velocity of 0.32 m/s to the Northwest. What is the final velocity of the red barge?Momentum - Impulse Obj : apply the law . In a system of colliding objects , the momentumis conserved. total momentum before a collusion is equal to the momentum after the collision m, v , + me v z - m , 1 3 mili + mzyz - mills = my 14 mz M 2 Va = mi Vit m zVz - miv3 = mzv4 m z M 2Physics - momentum and impulse Conservation of Momentum Problems 1. A 2. 5 kg ball traveling at J.Om/s collides head- oh with a 10.5 kg ball moving in the opposite direction at a speed of 6.0 m/s. The 2 5kg comes to a stop after the collision. What is the speed of the smaller ball after the collision ?
