A 100 pound force and a 150 pound force act on an object. If the angle between the force 40 degress, find the magnitude of the resultant force and the angle the resultant force makes with the 150 pound force.
The two pulleys connected by a belt have a radii of 15 cm and 8 cm. The larger pulley rotates 24 times in 36 seconds.
a. Find the angular velocity of the small pulley in radians per second.
b. Find the linear velocity of a point on the belt that connects the two pulleys in centimeters per second.
