## Homework Statement

The black curve represents the position of a spot on the x-axis projection of a spinning wheel.

a) Which curve represents the velocity of that spot? blue

b) What is the angular speed of the wheel?

c) What is the tangential speed of the wheel, assuming the full radius of the wheel is represented in this projection.

d) Does the x-projection have an angular acceleration at any time on the graph? Explain.

## The Attempt at a Solution

I have no idea how to read this graph. The only thing I can guess is that a) would be the blue line? Please help!
