got to know how high the pulley axles are.
Also, where on the circumference of B is the drop of paint at time t=0?
Then it's just a matter of knowing that A rotates twice as fast as B.
Two pullies are connected by a belt, Pulley A has a radius of 3 cm and pulley B has a radius of 6cm. As Pulley A rotates, a drop of paint on the circumference of pulley B rotates around the axle of Pulley B. Initially the paint drop is 7 cm above the ground determine the equation of a sinusoidal function that that describes the height of the drop of paint above the ground in terms of the rotation of pulley A
