The number of seconds that the ball will hit the ground will be 6 seconds.
It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
A ball is thrown vertically upward with an initial speed of 96ft/sec. Its height after t seconds is given by
h = - 16(t - 3)² + 144
Then the number of seconds that the ball will hit the ground will be
When the ball is on the ground, the height of the ball is zero. Then we have
0 = - 16(t - 3)² + 144
16(t - 3)² = 144
(t - 3)² = 9
t - 3 = 3
t = 6
