A rock is thrown vertically upward with a speed of 12.0 $\mathrm{m} / \mathrm{s}$ from the roof of a building that is 60.0 $\mathrm{m}$ above the ground. (a) In how many seconds after being thrown does the rock strike the ground? (b) What is the speed of the rock just before it strikes the ground? Assume free fall.
