    1. The problem statement, all variables and given/known data

    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?

    2. Relevant equations



    3. The attempt at a solution

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

    Yes, but after a couple of different attempts, i finally got the answer, it turns out my rounding was off by a couple of digits. But thanks anyways
