Final answer:
Jose can jump vertically the same height from a moving skateboard as from a stationary one, as horizontal motion does not impact vertical jump height according to the principles of physics.
Step-by-step explanation:
The question of whether Jose can jump vertically higher, lower, or the same height from a moving skateboard as compared to from a stationary skateboard is a matter of physics, specifically looking at the influence of horizontal motion on vertical jump height. The horizontal motion of the skateboard does not affect the vertical jumping capability because the vertical and horizontal components of motion are independent in the absence of air resistance. Hence, the height Jose can achieve with his vertical jump from the moving skateboard would be the same, assuming his technique and the power he exerts remain consistent.
