It would take 0.5 seconds for the ball to hit the ground.
To solve this problem, we are to use one of newton equations. Let us use:
s = ut + (1/2)gt²
Where u is the initial velocity = 88 ft/s, s is the height = 48 feet and g is the acceleration due to gravity = 32 ft/s²
Hence:
48 = 88t + 0.5*32*t²
16t² + 88t - 48 = 0
t = -6 or 0.5
Since the time cannot be negative, hence t = 0.5 seconds
It would take 0.5 seconds for the ball to hit the ground.
