Mathematics

$21.6\ s$

Step-by-step explanation:

Given

The initial velocity of the ball is $u=150\ ft\s$

Angle of projection $\theta=45^{\circ}$

The time of flight of the ball is given by

$T=\dfrac{2u\sin \theta}{g}\\\\$

Insert the values

$T=\dfrac{2\times 150\times \sin 45^{\circ}}{9.8}\\\\T=\dfrac{212.132}{9.8}\\\\T=21.6\ s$
