wf^2-wi^2=2a(theta) is what i'm thinking of using, but I don't know where to get (theta) in relation to the radius. i know that theta r = d, but theres no "d"
:(
1. Wheel A of radius 10 cm is coupled by belt B to a wheel C of radius 25 cm. Wheel A increases its angular speed from rest at a uniform rate of 1.6 rad/s^2. Determine the ime required for wheel C to reach a rotational speed of 100 rev/min, assuming the belt does not slip
2. I'm very...
