Homework Help: Physics

Posted by Anonymous on Tuesday, September 22, 2009 at 1:24am.

A particle P travels with constant speed in a circle of radius 8.6 m and completes one revolution in 12.0 s. The particle passes through O at t = 0 s. What is the magnitude of the average velocity during the interval from t = 5.4 s and t = 9.7 s?

What is the magnitude of the instantaneous velocity at t = 5.4 s?

What is the magnitude of the instantaneous acceleration at t = 9.7 s?

I have attempted this problem several times and cannot seem to arrive at the correct answers, so if someone could give me the answers, I would greatly appreciate it, and I could work backwards using my formulas. Thanks
