Answer:
Step-by-step explanation:
Given:
w = 4400 rev per minute
= 4400 × 2pi rad/1 rev × 1 min/60 sec
= 460.8 rad/s
R = 3cm
Ra = 18 cm
Since the sprocket is attached directly to the rear axle, it rotates exactly as the rear axle does: every revolution of the rear axle is a revolution of the sprocket. Hence, the angular speed of the rear axle sprocket = angular speed of the sprocket
= 460.8 rad/s
