Starting from rest, a wheel with a radius of 0.41 m begins to roll across the ground in a straight line under a constant angular acceleration of 6.09 rad/s2. What is the speed of the wheel in m/s after it has rotated through 18.5 full revolutions?
3. During a very quick stop, a car decelerates at 6.2 m/s2. Assume the forward motion of the car corresponds to a positive direction for the rotation of the tires (and that they do not slip on the pavement). a. What is the angular acceleration of its tires in rad/s2, assuming they have a radius of 0.28 m and do not slip on the pavement? b. How many revolutions do the tires make before coming to rest, given their initial...

Starting from rest, a disc with a radius of 0.69 m is subject to a constant angular acceleration of 5.89 rad/s2. What is the tangential speed of a point that is a distance of 0.43 m from the axis of rotation of the disc after 6.95 seconds?
A cyclist starts from rest and rides in a straight line, increasing speed so that her wheels have a constant angular acceleration of 2.0 rad/s2 around their axles. She accelerates until her wheels are rotating at 8.0 rad/s. If the radius of a tire is 0.31 meters, how far has the cyclist traveled? Answer in m (#10.9.5)

A spherical bowling ball with mass m = 3.8 kg and radius R = 0.106 m is thrown down the lane with an initial speed of v = 8 m/s. The coefficient of kinetic friction between the sliding ball and the ground is p = 0.33. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down...
