A ball thrown vertically upward from the top of a building with an initial velocity of v_A = 35 ft/s. Determine (a) how high above the top of the building the ball will go before it stops at B, (b) the time t_AB it takes to reach its maximum height, and (c) the total time t_AC needed for it to reach the ground at C from the instant it is released. 






h = 19.02 ft, t_AB = 1.087 s, t_AC = 3.30 s
