A ball is launched directly upward from ground level with an initial speed of 18 m/s. (Air resistance is negligible.)

(a) How long is the ball in the air?

(b) What is the greatest height reached by the ball?

(c) How many seconds after launch is the ball 7 m above the release point? s after being thrown (first time) s after being thrown (second time) Could someone show me how to set up and solve this problem?
