Answer:
180 m
Explanation:
The rock follows a free-fall motion - so the vertical distance covered can be found by using the equation
where
g = 10 m/s^2 is the acceleration due to gravity
t = 6.00 s is the time of the fall
Substituting these data, we find the height of the cliff:
The change needed is from 8 to 28, a change of 20 m/s. At a rate of 2m/s/s it will take 10 seconds for it to happen (2x10=20). I hope this helps.
