So i'm new to the Physics Forums and am looking for some help on this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Wheel A of radius r=10cm is coupled by belt B to wheel C with radius R=25cm.

the angular speed of wheel A is increased from rest at a constant rate of 1.6 rad/s^2.

Find the time needed for wheel C to reach an angular speed of 100 rev/min, assuming the belt does not slip (hint: the linear speeds of the two rims must be equal)

I get really confused whenever dealing with angular speed so if anyone could help that'd be great!

thanks

Jim

Can you offer guidance or do you also need help?
