Hello All, I am trying to figure out this problem, and any help would be great!(adsbygoogle = window.adsbygoogle || []).push({});

A Penguin moves in counterclockwise uniform circular motion. At one instant, it's centripetal acceleration (in m/s^2) is 6i + 4j. Three seconds later, the centripetal acceleration is 4i-6j.

A. What is the penguin's period?

B. What is the radius of the penguin's motion?

C. What is the penguin's speed?

I converted the unit vector forms into maginitude direction form, and found out, suppposing that in three seconds, the penguin did not complete a revolution, the period is four seconds.

But now I am trying to figure out the rest.

Sorry to be so arbitrary, but any hints?

Thanks!

Murphy :surprised
