Cyclist! A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. After 14 s, the wheels have made 48 rev. What is the angular velocity of the wheels after 14 s in rad/s ? rad/s Submit Answer Tries 0/2 What is the angular acceleration of the wheels in rad/s² ? rad/s² Submit Answer Tries 0/2 If the radius of the wheel is 37 cm, and the wheel rolls without slipping, how far has the cyclist (in m) traveled in 14 s? m Submit Answer Tries 0/2
A baseball pitcher brings his arm forward during a pitch, rotating the forearm about the elbow. v= 35.5 m/s d=0.29 m If the velocity of the ball in the pitcher's hand is 35.5m/s and the ball is 0.29 m from the elbow joint, what is the angular velocity (rad/s) of the foerarm?
A rotating wheel requires 5.00 s to rotate 29.0 revolutions. Its angular velocity at the end of the 5.00-s interval is 96.0 rad/s. What is the constant angular acceleration (in rad/s) of the wheel? rad/s2
5) A disk of mass m = 75.0 g and radius r = 4.20 cm glides across an air table at a speed v = 1.5 m/s. It makes a glancing collision with a hoop of radius R = 5.80 cm and mass M = 130 g (initially at rest) such that their rims just touch. Because their rims are coated with instant-acting glue, the two objects stick together and rotate after the collision. a) What is the angular momentum of the system relative to the center of mass? b) What is the angular speed about the center of mass?
