Question

A pulley of radius 10 cm turns at 6 revolutions per second. What is the linear velocity of the belt driving the pulley in meters per second?. possible answers:. A. 376.99 m/s. B. 1.67 m/s. C. 166.67 m/s. D. 3.77 m/s

Answer 1

We calculate as the linear velocity of the belt driving the pulley as follows:

angular velocity is related to linear velocity by the equation

v = wr

where v is the linear velocity, w is the angular velocity, and r is the radius.

v = 6 x 2π x 10
v = 376.99 m/s

Therefore, the correct answer is option A.
