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 confused by what exactly I have to solve for first. I know that I have to use the 5 equations of motion (with the rotation variables subbed in for the linear ones) but I'm still not sure.

3. I thought that since the radius of C is A*2.5, I thought about solving for A, and then multiplying by 2.5, but I don't know... Can someone please show me how to do it?
