A fly sits on a potter’s wheel 0.30m from its axel. The wheel’s rotational speed decreases from 4.0 rad/s to 2.0 rad/s in 5.0s. Determine  The wheel’s average rotational acceleration.  The angle through which the fly runts during the 5.0s  The distance traveled by the fly during that time interval.

A child with mass 42 kg sits on the edge of a merry-go-round at a distance of 3.0 m from its axis of rotation. The merry-go-round accelerates from rest up to 0.40 rev/s in 10 s. a. What is the angular acceleration of the merry-go-round? Express this in radians/second. b. What is the angular velocity at 5 s? c. Calculate the centripetal acceleration and tangential acceleration at 5 s. d. What is the total acceleration at 5 s? e. If the coefficient of static friction between the child and the surface of the merry-go-round is 0.6, does the child fall off before 5 s? Hint: To determine this, calculate the frictional force and force due to the acceleration of the merry-go-round on the child. Compare the two forces to find which is larger than the other, therefore overcomes the other.

At a time of 13D0 seconds the tires of a moving motorcycle are rotating with an unknown initial angular velocity, at that instant each tire starts accelerating with an angular acceleration of 3.00 rev/s2 for 5.00 seconds. Each tire turns through 50.0 revolutions in those 5.00 seconds. Assume the motorcycles tires have a radius of 36.0 cm and that the tires rotate without slipping relative to the road surface. How fast is the motorcycle traveling at t=5.0s?
