Question

a pulley with a radius of 12 cm turns at 7 rps. what is the linear velocity of the belt driving the pulley in meters per second?

Answer 1

The belt that is driving the pulley moves at a linear speed of 1.71 meters per second.

How fast is it moving along a line?

When an object moves in a straight line or following a predetermined axis, this is referred to as linear velocity. A moving body's velocity, on the other hand, denotes the distance it covers in a certain amount of time and in a particular direction.

Finding linear velocity in meters per second: what formula do you use?

A point's linear speed is therefore equal to its angular speed times the distance r. This measurement is done in meters per second and metres per second. where, = speed in radians per second.

Speed is expressed in radians per second, therefore = 12/7 = 1.71 meters per second.
