A point starts at the location ( – 5,0) and moves CCW along a circle centered at (0, 0) at a constant angular speed of 2 radians per second. Let t
represent the number of seconds since the point has swept out since it started moving. Draw a diagram of this to make sure you understand the
context!
a. Suppose the point has traveled for 0.1 seconds (t = 0.1). How many radians would need to be swept out from the 3-o'clock position [or from
(5, 0)] to get to the point's current position?
b. Write an expression in terms of t to represent how many radians would need to be swept out from the 3-o'clock position to get to the point's
current position.

- Determine the polar moment of inertia of the area shown with respect to point O. Hint: your calculations should show J (semi-circle) – J (rectangle). For extra credit: Find the polar moment of inertia about the centroid of the area. Extra credit hint: Apply the PAT one time for the whole shape. Once you know "a" moment of inertia for a shape, you can apply the PAT to that shape. This is a "sneaky" way to find the moment of inertia about a centroid location. We can apply PAT to any shape – it does not have to be one of the standard shapes we find in a published table.)
