Thread: [SOLVED] Trigonometry test question

There are three rollers under a conveyor belt, and each roller has a radius of 8 centimeters. The rollers turn at a rate of 2 revolutions per second. What is the linear velocity of the conveyor belt? (the centimeters has to be converted into meters.)

PLEASE HELP ME. THANKS.

The question you are asking seems to be a basic question of physics.

the linear velocity of any point rotating about a fixed axis with an angular velocity of is where r is the distance between the point and axis.

The conveyor belt must be moving at the same speed as the rollers (at the point of contact ) therefore where r is the radius of the rollers i.e. 0.08 m. remember is the rate of change of the angle . the rollers turn 2 revolutions in a second .therefore they turn at the rate of per second .
