Question

Which of the following statements is TRUE? In this lab, we define the system as the two carts, the track, and the earth. Momentum is always conserved within a system no matter how we choose the system. In everyday life, completely inelastic collisions are relatively easy to observe compared to elastic collisions. In everyday life, elastic collisions are relatively easy to observe compared to completely inelastic collisions. Which of the following statements about two carts rolling on a track and experiencing a completely inelastic collision is TRUE? The momentum of the system is conserved to good approximation. The sum of the velocities of the two carts just before and just after the collision is approximately the same. The kinetic energy of the system is conserved to good approximation. According to this experiment, which of the following statements is TRUE? "Massive" means to add weights to both carts. If you accidentally touch a cart during a collision, the momentum of the system is still probably conserved. "Massive" means to add weights to a single specified cart. You must continue to push cart #1 during the collision to complete the motion. To approximate an elastic collision in this experiment, you should: Take off the magnets to allow a sharp contact during collision Orient the carts so that the Velcro strips face each other. Take off the Velcro strips. Orient the carts so that the magnets attached to the carts face each other.

Explanation / Answer

The statement (3) is correct in the first question. all the accedents are inelastic collisions.

The statement (1) is correct in the second question. because, we take, the momentum is conserved in both elastic collision and inelastic collisions.

The statement (3) is correct in the third question.

The statement (4) is correct in the fourth question, if magnets attached to carts, they did not touch each other while collision due to repulsion force, so, there is no loss of kinetic energy. due to this kinetic energy is conserved. that is it becomes a elastic collision.
