What has the larger velocity?

In reference to the picture down, if the same object moved in the way of the red arrow and moved in the way of the blue arrow (both ways leading to the floor). What way has the biggest velocity? Explain. Is there any other assertion you can add in the distinctions between the red and the blue arrows?


Velocity Referenced to the ground. 

Arrows don't indicate V.

    Conservation of energy leads to V = √2gh 

    since h is the same, then final speed V is the same either : time, of course, will be different !!!

    Applying  standard physics assumptions (no friction or air drag etc etc) , then the object  will acquire  the same velocity on reaching the ground no matter if it follows the path of the blue or red arrow. In other words,  the velocity acquired by the object  is independent of the path taken. Gravity is a conservative force.

    If the incline is frictionless, the same velocity is acquired by either route.

    If the incline is NOT frictionless, the vertical path attains the higher velocity.

    Velocity has units of meters per second: m/s. If the longer distance is traveled in the same time as the shorter, it is the higher velocity.

    velocity referenced to what? assuming the ground, which is largest is unknown as we have no idea of the parameters. 

    Guessing, if the length of the arrows indicates the velocity, then the red one has the largest magnitude of velocity.

    OR, if you have a body falling (blue) versus sliding down the slope (red) then blue would have the highest velocity. 

    altogether very vague.
