Question

URGENT!!!!!!!!!!!A bicycle is clamped upside down on a workbench for the bicycle repair woman to repair a front wheel axle. she gives the front wheel a spin with her hand, and the wheel rotates at 5.0 rev/s. what is the angular velocity of the wheel? if the moment of inertia of the wheel is 0.060 kg.m^2 ,what angular impulse did the repair women give the wheel?

Answer 1

Explanation:

w = 2π(5.0 rev/s) = 31 rad/s

Angular Impulse = Li - Lf = l (w1 - w2)

= (0.060 kg.m^2) × (31 rad/s - 0 rad/s)

= 1.9 N•m•s
