Homework: Elastic Colli. https://www.flipitphysics.com/Course ViewProblemrunitlternl): 33591 658 enrollmentID-300639 Two masses slide on frictionless air track. The first block with mass (unknown) has initial speed vi = 4.2 m/s to the right. The second block with mass m2 (unknown) has initial speed v2 3.3 m/s to the left. The two blocks go through a variety of collisions described below but each with the same initial conditions described above). Elastic Collision nteractive Example IE Collision with Friction IE Spring Loaded_collision 1 After the collision, mass mi rebounds back to the left with speed vit 2.3 ms and the mas m rebounds to the right Standand Exerclse Billard Balls (w Work) with speed t5.2 m/s. Which of the following statements are true about the two block system? Both mo entum and mechanical energy are conserved within the two block system. only momentum is conserved within the two block system. Slerrd Exercise Bumper Cars Only mechanical energy is conserved within the two block system. Neither momentum nor mechanical energy are conserved within the two block system. More information is needed to determine if momentum and mechanical energy of the two block system are Bumper Cars 2 Optional Sutxnil Standand Exerclse Tipler6 8.P.017 Optional pler6 8.P.021 Optional 2) After the cosion, mass m1 continues to move to the right with speed vir1.4 m/s and the mass m2 rebounds to the right with speed vzt 4.8 m/s. Which of the following statements are true about the two block system? Both momentum and mechanical energy are conserved within the two block system. Only mechanical energy is conserved within the two block system. Tipler6 8.P.059 Optional Only momentum is conserved within the two block system. Neither momentum nor mechanical energy are conserved within the two block system. Tipler6 8.P.061 Optional More information is needed to determine if momentum and mechanical energy of the two block system are Subrnit ipler6 8.P.062 Optional 2018-03-04 20Explanation / Answer
1) Since it is elastic collision, therefore
both momentum and mechanical energy are conserved within the two block system.
2) Here also
both momentum and mechanical energy are conserved within the two block system.
3) Here
Only momentum is conserved within the two block system.
4)
both momentum and mechanical energy are conserved within the two block system.
5)
both momentum and mechanical energy are conserved within the two block system.
