Question

A rock is thrown from a bridge at an angle 30 degrees above the horizontal. Immediately after the rock is released, is the magnitude of its acceleration greater than, less than, or equal to g? Explain.

Answer 1

The magnitude of acceleration of the rock immediately after it is released is equal to the acceleration due to gravity, g.

Step-by-step explanation:

The magnitude of acceleration of the rock immediately after it is released is equal to the acceleration due to gravity, g. The magnitude of acceleration of the rock immediately after it is released is equal to the acceleration due to gravity, g.

In this case, g is approximately 9.8 m/s^2. The rock only experiences acceleration in the vertical direction due to gravity, while the horizontal component of its velocity remains constant. Therefore, the magnitude of its acceleration is equal to g, and it is greater than 0 since it is directed downward.

The magnitude of acceleration of the rock immediately after it is released is equal to the acceleration due to gravity, g.
