A ball is thrown down vertically with an initial speed of 22 ft/s from a height of 34 ft.
(a) What is its speed (in ft/s) just before it strikes the ground?
(b) How long does the ball take to reach the ground?
(c) part a and (d) part b if the ball were thrown upward from the same height and with the same initial speed ? Before solving any equations, decide whether the answers to (c) and (d) should be greater than, less than, or the same as in (a) and (b).
