A 0.300 kg block is pressed against a spring with a spring constant of 8050 N/m until the spring is compressed by 6.00 cm. When released, the block slides along a horizontal surface that is frictionless except for a 7.00 m long rough section.
a) The block comes to a stop exactly at the end of the rough section. What is the coefficient of kinetic friction between the block and the rough section?
b) The rough section is now polished, so that the entire track is frictionless. The block slides along the surface and into the circular loop at the end. If the normal force between the loop and the block is 90.0 N when the block reaches point P (the exact top of the loop), what is the radius R of the circular loop?

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?
