The acceleration of the rock would be 8 meters/second².
The rate of change of the velocity with respect to time is known as the acceleration of the object.
As given in the problem a mountain goat starts a rock slide and the rocks crash down the slope 100 m. If the rocks reach the bottom in 5 s,
initial velocity of rock = 0 m/s
displacement = 100 meters
time = 5 seconds
s = ut + 0.5at²
100 = 0 + 12.5a
a = 100/12.5
= 8 meters/second²
Thus, the acceleration of the rock would be 8 meters/second².
