Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. (a) If the faster stone takes 10 s to return on the ground, how long will it take the slower stone to return? (b) If the slower stone reaches a maximum height of H, how high (in terms of H) will the faster stone go? Assume the two stones are freely falling objects.

A 4.0-g bullet leaves the muzzle of a rifle with a speed of 340 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.75-m-long barrel of the rifle?
Suppose that 4% of all TVs made by A&B Company in 2000 are defective. If eight of
these TVs are randomly selected from across the country and tested, what is the
probability that exactly three of them are defective? Assume that each TV is made
independently of the others.
