One object moves in the positive x direction with speed v. Another object moves in the opposite direction with the same speed, but with one‑third the mass of the first object. The two objects have a completely inelastic collision. What is the final x component of the velocity?

If the speed of a particle triples ,by what factor does its kinetic energy increase?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
