Q. A superball of mass = 50 g, initially held at rest, is dropped from a height of = 1.5 m. It collides with a table, then bounces up to a height of = 1.0 m. The duration of the collision (the time during which the superball is in contact with the table) is = 15 ms (). In this problem, take the positive y direction to be upwards, and use for the magnitude of the acceleration due to gravity.

Q. A 02385 mH inductor has a length that is four times its diameter. If it is wound iwth 10.3 cm^-1 truns per centimeter, what is its length? Answer in units of m.
