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.
A bicycle is turned upside down while its owner repairs a flat tire. A friend spins the other wheel, of radius 0.357 m, and observes that drops of water fly off tangentially. She measures the height reached by drops moving vertically. A drop that breaks loose from the tire on one turn rises h = 54.2 cm above the tangent point. A drop that breaks loose on the next turn rises 51.0 cm above the tangent point. The height to...
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...

You have your bicycle upside-down for repairs. The front wheel is free to rotate and is perfectly balanced except for the 34 g valve stem. 1.If the valve stem is 34 cm from the rotation axis and is located 24 ∘ below the horizontal, what is the resulting torque about the wheel's axis?
A bicycle wheel has four firecrackers attached to it on opposite ends of the wheel's diameter, as shown in the figure to the right. When the firecrackers are lit, they release heated gas away from their front ends. The bicycle wheel is pivoted against a wall by its center of mass and is free to spin. a. Which way will the bicycle wheel spin when the firecrackers are lit? Explain using the torque right hand rule. b. What is the...
A bicycle racer is going downhill at 14.0 m/s when, to his horror, one of his 2.50-kg wheels comes off when he is 67.0 m above the foot of the hill. We can model the wheel as a thin-walled cylinder 85.0 cm in diameter and neglect the small mass of the spokes. Part A How fast is the wheel moving when it reaches the foot of the hill if it rolled without slipping all the way down? Express your answer...
