Question

A rock is thrown upward from the edge of a cliff that is 20 m high. The object rises 15 m and then falls to the ground. If the positive direction of the x is up, what is the rock's displacement?

Answer 1

The rock's displacement can be calculated by subtracting the initial position from the final position. In this case, the initial position is 0 m (ground level), and the final position is 15 m (the highest point reached by the rock).

To find the displacement, we subtract the initial position from the final position:

Displacement = Final position - Initial position

Displacement = 15 m - 0 m

Displacement = 15 m

Therefore, the rock's displacement is 15 meters.
