a skateboarder rolls off a ramp at a constant horizontal speed. what happens to the vertical velocity of the skateboarder after they leave the ramp? it decreases in the downward direction. it remains constant because the horizontal speed is constant. it becomes zero and stays zero. it increases in the downward direction.

a skateboarder rolls off a ramp at a constant horizontal speed. what happens to the vertical velocity of the skateboarder after they leave the ramp? it decreases in the downward direction. it remains constant because the horizontal speed is constant. it becomes zero and stays zero. it increases in the downward direction.

Answer

Explanation:

Step1: Consider gravitational force

Gravity acts downward on the skate - boarder.

Step2: Analyze vertical motion

The acceleration due to gravity ($g = 9.8\ m/s^{2}$) causes a change in vertical velocity. Since the acceleration is in the downward direction, the vertical velocity of the skate - boarder increases in the downward direction.

Answer:

It increases in the downward direction.
