Answer:
27.4 ft
Step-by-step explanation:
assume acceleration due to gravity is 32.2 ft/s² acting downwards,
hence acceleration acting on the ball is a = -32.2ft/s²
using the acceleration velocity equation
v1² = v0² + 2as
where .
v0 = inital velocity = given as 42 ft/s
v1 = final velocity = 0 (velocity is zero at maximum height)
s = height
0² = 42² + 2(-32.2) s (solve for s)
s = 27.4 ft
