Ferris wheel

  1. Sep 8, 2003 #1
    The problems reads, A carnival Ferris wheel has a 14.2m radius and completes one revolution about its horizontal axis in 10.1s. Consider the time interval from the instant when a passenger is at the lowest point of the uniform circular motion to a clock reading 5.05 seconds later. What was the magnitude of the passenger's average acceleration during this time interval?


    Do I use the formula (they're suppose to be vectors) a=(-rwcoswt)i+(-rwsinwt)j? I really don't have any direction towards solving this problem. Any hints would be wonderful.

    That should be:

    a=-rω2cos(ωt)i-rω2sin(ωt)j

    You forgot to square the angular velocity, but other than that it's OK.
