Homework Statement



Ive have tried it so many times but cant get the right answer but the problem is: Your roommate is working on his bicycle and has the bike upside down. He spins the 54.0 cm-diameter wheel, and you notice that a pebble stuck in the tread goes by three times every second. What is the particles speed? and then what is the particles acceleration?

How have you attempted this problem? If it goes by 3 times every second, how much distance is it covering in 1 second?
