Use a(t) = -9.8 meters per second per second as the acceleration due to gravity. (Neglect air resistance.)

Question

A baseball is thrown upward from a height of 3 meters with an initial velocity of 7 meters per second. Determine its maximum height. (Round your answer to two decimal places.)

Answer 1

v = vi - a t
0 = 7 - 9.8 t
t = 7/9.8 at top when v = 0

h = 3 + 7 t - 4.9 t^2
