While working on her bike, Amanita turns it upside down and gives the front wheel a counterclockwise spin. It spins at approximately constant speed for a few seconds. During this portion of the motion, she records the x and y positions and velocities, as well as the angular position and angular velocity, for the point on the rim designated by the yellow-orange dot in the figure. View Figure Let the origin of the coordinate system be at the center of the wheel, the positive x direction to the right, the positive y position up, and the positive angular position counterclockwise. The graphs View Figure begin when the point is at the indicated position.(adsbygoogle = window.adsbygoogle || []).push({});

Which of the graphs corresponds to x position versus time?

-> would this be a [ C ] because the position doesn't move as time passes by? Or is this different for rotational?

Which of the graphs corresponds to angular position versus time?

Would this be [ E ] since it starts with position 0, then it goes to a positive position, then negatice, to posive etc?

Which of the graphs corresponds to y velocity versus time?

What do they mean by y velocity? (verticle velocity)

would the verticle velocity do negative to positive and back to negative again? Is this possible? so graph [ G ] ?

Which of the following graphs corresponds to angular velocity versus time?

I have no idea...

Thanks
