Question

Did an expiment in which a light cart collided into a heavy cart and vice versa to be an elastic collision. we then did the same but with velcro so it was an inelastic collision

1. Do you need to take into account the direction of the velocities of the carts before and after the collision when you calculate Kinetic energy? Why or why not?

2. Assume that you will do the elastic collision heavy into the light cart experiment one more time, and instead of launching the heavy cart you are pushing it all the time (before and even after the collision). What could you say about the conservation of momentum in this case, is it conserved?

3. Assume that you will do the experiment one more time but the dynamic track is not level, should the linear momentum be conserved in this situation? Why or why not?
