Homework Help: Physics

Posted by Alphonse on Friday, October 26, 2012 at 2:03am.

You are riding a merry-go-round on the rim which is turning counterclockwise at a constant angular speed of 0.5 rad/s.  Your dog sees you at the 12 o'clock position when he is at the 3 o'clock position.  He starts running counterclockwise from rest with an angular acceleration of 0.31 rad/s2.  The merry-go-round has a radius of 3.36 m.
 
a) When does your dog first catch up to you?

b) How fast is your dog running (in m/s) at the instant you computed in part a?
