Document Summary
Solve the following problems in the space provided. Use the back of the page if needed. You must show your work in a logical fashion starting with the correctly applied and clearly stated physical principles. The equations you need are on the equation sheet. Using the free body diagram at the right we can apply the second law, Solving the x equation for the friction and the y equation for the normal force, Substituting into the definition of the coefficient of friction, . Fall 2013: below are depictions of five balls on the ends of light strings spinning in circles at identical constant speeds. The speed is large enough to keep the balls in circular motion. The strings are all the same length, but the masses of the balls are different as indicated. Rank these situations from greatest to least based upon the (a)centripetal acceleration, (b)tangential acceleration, and (c)tension in each string.
