at point no. 2 in the diagram, let the object accelerates to a velocity v1 (just along the direction of the slope) due to rolling down the ramp. Now, v1 has a x-component as well as y-component.
Now, my question is:
In the diagram, In between the points no. 2 and 3, the object passes over a horzontal distance. During this part of motion, which statement of the following is true:
i) the magnitude of the velocity remains constant, i.e. equal to v1, and only the direction changes.
or, ii) the magnitude of the velocity changes, in such a way, that only the x-component of v1 remains still; whereas, the y-component of v1 completely vanishes, as soon as the object leaves the ramp and gets onto the horizontal trajectory(between the points marked 2 and 3).
