The sphere is raised at an angle of 15 above the sphere's equilibrium position and then released from rest so that the pendulum oscillates, as shown in the figure. Location 1 is shown in the figure. A graph of the pendulum's horizontal position as a function of time is shown in the graph. (a) The dot below represents the sphere at location 2. Draw a free-body diagram that shows and labels the forces (not components) exerted on the sphere at the location. Draw the relative lengths of all vectors to reflect the Page 4 of 9 AP Physics 1 AP CollegeBoard Test Booklet Unit2DynamicsFRQ relative magnitudes of all forces. Location 2 (b) Calculate the maximum kinetic energy of the sphere as it oscillates.HD 1 461| 4A T Q860 1:38 AP CollegeBoard Test Booklet Unit2DynamicsFRQ relative magnitudes of all forces. 5/9 Location 2 (b) Calculate the maximum kinetic energy of the sphere as it oscillates. The sphere is raised to a new angle above the sphere's equilibrium position that is less than the angle described for part (a). The sphere is released from rest so that the pendulum oscillates. (c) Explain how the motion of the sphere changes, if at all, based on the appropriate evidence. AP Physics 1 Page 5 of 9 AP CollegeBoard Test Booklet Unit2DynamicsFRQ 3.

The opposite is true for the person: air resistance on the person is negligible, but the person's shoes do not slip on the ice. The table shows the force exerted by the person on the block for several values of constant
