Rotational Motion Speed at the top of the loop

  1. Oct 31, 2011 #1
    1. The problem statement, all variables and given/known data

    12. A motorcycle travels around a vertical 12 m radius loop. What is its speed at the top of the loop if the normal force exerted by the seat on the driver is equal to ΒΌ of his weight?

    a. 7 m/s

    b. 8.1 m/s

    *c. 9.4 m/s

    d. 15 m/s

    e. 88 m/s

    2. Relevant equations


    3. The attempt at a solution

    I did (1/4)W=m(v2/r)-W and I got 12.1 m/s
