2π(15)/(2π(8)) = 1.875 or 15/8
so for each rotation of the large pulley, the smaller rotates 1.875 times or 15/8 times.
angular velocity of large one = 25(2π)/36 radians per second
= 25π/18 rad/s
angular velocity of smaller = (15/8)(25π/18) rad/s
= 125π/48 rad/s
The 2 pulleys in the figure have radii of 15 cm and 8 cm, respectively. The larger pulley rotates 25 times in 36 seconds find the angular velocity of each pulley in radians per second. Find angular velocity of each pulley in radians per second.
