Test Scenario: Uniform Circular Motion

Printer Friendly Version

This scenario is based on the 1999 AP B exam's FRQ #5.

Refer to the following information for the next eight questions.

A coin of mass 25 grams is placed 20 cm from the center on a horizontally rotating turntable. The coin does not slip while the platform rotates at a constant angular speed of 75 rpm.

(a) What is the frequency of the turntable in revolutions/sec?

(b) What is the period of the turntable?

(c) What is the magnitude of the coin's linear velocity in m/sec?

(d) Which of the following diagrams correctly illustrates the direction of the coin's linear velocity at the instant it is at the position shown in the diagram above?

(e) Which of the following diagrams correctly illustrates the direction of the coin's acceleration at the instant it is at the position shown in the diagram above?

(f) What would be the magnitude of the acceleration experienced by the coin?

(g) Determine the coefficient of static friction required between the coin and the surface for the coin to stay in place while the turntable rotates.

(h) If the first coin were to be replaced with a larger, more massive, coin made of the same material, which of the following statements is true?

the larger coin will fly off at a tangent
the larger coin will remain at rest as well
the larger coin will fly off along the radius
the larger coin will spiral in towards the center of the turntable
