An automobile with 0.245 m radius tires travels 8.6 X 104 km before wearing them out. HOW many revolutions do the tires make, neglecting any backing up and any Change in radius due to wear? revolutions You observe a microwave oven rotating at a rate of about 6.6 rpm. What is this angular velocity in radians per second? rad/s A baseball pitcher brings his arm forward during a pitch, rotating the forearm about the elbow. If the velocity of the ball in the pitcher's hand is 36.5 m/s and the ball is 0.350 m from the elbow joint, what is the angular velocity of the forearm? m/sIn lacrosse, a ball is thrown from a net on the end of a stick by rotating the stick and forearm about the elbow. If the angular velocity of the ball about the elbow joint is 31.5 rad/s and the ball is 1.27 m from the elbow joint, what is the linear velocity of the ball? m/s
