**Wheel A of radius ra = 14.6 cm is coupled by belt B to wheel C of radius rc = 28.8 cm. Wheel A increases its angular speed from rest at time t = 0 s at a uniform rate of 7.1 rad/s2. At what time will wheel C reach a rotational speed of 240.7 rev/min, assuming the belt does not slip?**

*I did ...Vta = Vtc, but stil didint get it. i got the Vtc*

value and divided that by raduis of A to get w for a. then

divided the acceleration by the w for a, but my time is

still wrong!
