Your roommate is working on his bicycle and has the bike upside down. He spins the 56.0 cm -diameter wheel, and you notice that a pebble stuck in the tread goes by three times every second. What is the pebble's speed? What is the pebble's acceleration?
Your roommate is working on his bicycle and has the bikeupside down. He spins the 62.0 -diameter wheel, and you notice that a pebble stuck in thetread goes by three times every second. What is the pebble's speed? and what is thepebbles acceleration? are the two questions I must answer. I haveno idea how to set up this problem. Please help. Thanks.
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 rimdesignated by the yellow-orange dot in the figure. (Intro 1 figure) Let the origin of the coordinate system be at the center of the...
