The time taken by the rock will be 8.77 seconds.

<h3>What is speed?</h3>

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

The equation for free fall at the surface of some planet (s in meters, t in seconds) is s = 2.86t²

The time will be calculated by using the speed formula.

Speed = Distance \ Time

25.1 = 2.86t² \ t

t = 25.1 / 2.86

t = 8.77 seconds

Therefore the time taken by the rock will be 8.77 seconds.
