Linear speed at the North Pole or South Pole linear speed at

Linear speed at the North Pole or South Pole linear speed at Quito, Ecuador, a city on the equator linear speed at Salem, Oregon (halfway from the equator to the North Pole) Speeds of a Pulley and a Belt The pulley shown has a radius of 12.96 cm. Suppose it takes 18 sec for 56 cm of belt to go around the pulley. Find the linear speed of the belt in centimeters per second. Find the angular speed of the pulley in radians per second.

Solution

a) linear speed of belt = distancetravelled by belt/time = 56/18 = 3.11 cm/sec

b) angular speed = linear speed of belt/radius = 3.11/12.96 = 0.24 rad/sec
