1. Match the Values with thier standard units: Momentum Mass Velocity Acceleration Displacement Time Force 2. Two objects of mass 8.9kg, are about to collide elastically. Before thier collision, the velocity of object 1 was 21.4m/s and object 2 was 0m/s. What is the Velocity Object 2 after this collision. Use the Elastic Collisions equation 3. Three objects are sliding(with no friction) along the ground. Assume that all three objects are on a trajectory so that tbey are about to collide with each other. Object 1 is 4kg and is moving to the right at 9.2m/s Object 2 is 13kg and is at rest Object 3 is 8kg and is moving to the left at 3.8 m/s What is the total momentum of this system at this time, before objects collide 4. A 2.5 object is moving at -9.7m/s. What is the momentum of this object. 5. Three objects are slicing (with no friction) along the ground. Assume that all three objects are on trajectory so that they are about to collide with each other. Object 1 is 3kg and is moving to the right at 8.9m/s Object 2 is 17kg and is at rest Object 3 is 7kg and is moving to the left at 5.8m/s What is the total momentum of this system AFTER they collide with each other. Right is postive direction and left is negative
