Solution 1

To find the time when the stone hit the ground, we can use the given velocity equation v(t) = -32t. We know that the velocity was -152 ft/s when it hit the ground. So, we can set up the equation as follows:

-152 = -32t

To solve for t, we divide both sides of the equation by -32:

t = -152 / -32
