Answer:
The answer is C!
Step-by-step explanation:
The ball's acceleration is the rate of change of its velocity, and its velocity is the rate of change of its height. So if is the ball's height at time , then
The ball is dropped from , and since it's being dropped there is no additional velocity added to it, so .
Integrating both sides of the ODE gives
and since , we have .
Integrating again gives
and since , we get
So the ball's height at any time is governed by
The ball hits the ground when :
