need help

good day I need help


a belt is driven by a pulley at 33m/s the pulley rotates at 750 r/min. calculate:

(a) the rotational frequency in r/s

(b) the diameter of the drive pulley

(a) What do you need to do to 750 r/min to find the number of rotations per second (r/s)?

(b) Can you use that result along with the speed of the belt to answer this part?

If the pulley has diameter d and makes n revolutions per second, n × $\pi$d = 33 m.
