Answer:
9
Step-by-step explanation:
Area of a triangle=(base*height)/2
1) Input the values
54=(12h)/2
2) Multiply both sides by 2
54*2=(12h/2)2
108=12h
3) Divide both sides by 12
108/12=12h/12
9=h

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.
