An engineer wants to design a circular racetrack of radius L such that cars of mass M can go around the track at speed U without the aid of friction or other forces other than the perpendicular contact force from the track surface.
Suppose the race cars actually round the track at a speed w>U. What additional radial force Fr is required to keep the cars on the track at this speed? Express the answer in terms of M, L, U, w, and g.
There is a question like this on but it doesn't have the right answer.

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?
