To find the acceleration of the rock, we can use the formula:
acceleration = (final velocity - initial velocity) / time
Substitute the given values:
acceleration = (31.6 m/s - 12.0 m/s) / 2.0 s
acceleration = 19.6 m/s / 2.0 s
acceleration = 9.8 m/s^2
Therefore, the acceleration of the rock is 9.8 m/s^2.
acceleration = (final velocity - initial velocity) / time
Substitute the given values:
acceleration = (31.6 m/s - 12.0 m/s) / 2.0 s
acceleration = 19.6 m/s / 2.0 s
acceleration = 9.8 m/s^2
Therefore, the acceleration of the rock is 9.8 m/s^2.
