We know that the stone's velocity was −152 ft/s when it hit the ground. Therefore, since v(t) = −32t, the time when the stone hit the ground wast = s.
Question
We know that the stone's velocity was −152 ft/s when it hit the ground. Therefore, since v(t) = −32t, the time when the stone hit the ground wast = s.
Solution
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
This gives us:
t = 4.75 seconds
So, the stone hit the ground after 4.75 seconds.
