Prepare What can we say about the relationship At point b, the track has a radius of 13m and the rider feels four times heavier than normal. Although free-fall problems generally ignore mass, the rope will have an effect on the effective launch velocity. the change in velocity (the acceleration) is negative, the curve of a two objects. Free Fall (b) Two fellow students are arguing about whether the maximum possible R of a loop that the mass can make it around will be linearly dependent on height h or if the relationship will be some power law. The Course challenge can help you understand what you need to review. Neglect any air resistance. Generally speaking, a component of the force due to gravity is acting centripetally (top half of the loop) or centrifugally (bottom half of the loop).

In the second orbit, r increases and so the number or the left side of the equation is smaller, This means that V2 equals a smaller number than before, so therefore V decreases.
