<h3>
Answer: 130 meters</h3>
===================================================
Explanation:
vi = 5 and vf = 8 are the initial and final velocities respectively. The change in time is t = 20 seconds.
So,
x = 0.5*(vi + vf)*t
x = 0.5*(5+8)*20
x = 130 meters
represents the distance traveled. The first equation shown above is one of the four kinematics equations.
The force ffrom the ground that holds the rock up and prevents her from falling through the gound, unless the ground breaks.
