Answer:
The rock will hit the ground at 20.44 m from the point of the drop
Step-by-step explanation:
Horizontal Motion
It occurs when an object is thrown horizontally from a height h at an initial speed v.
The range or maximum horizontal distance traveled by the object can be calculated as follows:

When the small rock is dropped from a car at speed v=32 m/s, it starts a curved path that ends up when the rock hits the ground. The height is h=2 m, thus the range is:



The rock will hit the ground at 20.44 m from the point of the drop
