Question

A golf ball is hit from the ground with an initial speed of 192 feet per second. Assume the starting height of the ball is 0 feet. How long will it take the golf ball to hit the ground?

Answer 1

assume g = -32 , u = 192, s = 0, t = ?

using the formula

s = ut + 0.5gt^2
0 = 192t - 16 t^2
16t( t - 12) = 0
t = 12 seconds
