The distance traveled as a function of time is given by . Since, for this problem, the initial velocity is zero and the initial distance traveled is zero, this reduces to . From the given information, we know this to be equal to 75 meters.
The velocity as a function of time is given by . Since the initial velocity is zero for this problem this reduces to . From the given information we know this to be equal to 25 meters per second.
Hence:
So
So the elapsed time at the point the distance was 75 meters and the velocity was 25 meters per second is 6 seconds. Since
