A ball is thrown in the air with velocity of 50.0 m/s, assuming no air resistance calculate its maximum height.

Use SUVAT equations to find height, S, when final velocity, V, is 0: s = ?u = 50 m/sv = 0 m/sa = -9.81 m/st = Not necessaryRecall: v 2 = u 2 +2as s = -u 2 /(2a) = -2500/(2 x -9.81) = 127.4 m But given to 3 s...
