(c) The first spacecraft is moved into a new circular orbit that has a radius greater than R, as shown in the figure below. 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).

The tension will be lower at point B than it is at the bottom as there is a component of gravity helping the tension in the centripetal direction (as opposed to gravity acting centrifugally at point A): FcA = FcB = mv2/R TA mg = TB + mg sin 30 = mv2/R TB = TA mg(1 + sin 30) (ii) Constant tension will result in a much higher speed at point B as the tension will be locked in at TA above. Identifying Provide evidence for your claim. Prepare What is the linear?

(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. Sketch a velocity vs. time, position vs. time, Single-select questions are each followed by four possible responses, only one of which is correct. If the normal force goes to zero, this indicates a loss of contact between the sliding mass and the track.
