The neighborhood kids go to the playground and find a box turtle with a mass of about 550g. They put him on the merry-go-round about 0.890m from the center and push the merry-go-round so that it rotates at 2.35 m/s. (a)Draw a free body diagram. (b) what is the source of the centripetal force? (c) What is the minimum coefficient of static friction so that the turtle does not slide off?
