w = 3.5 rad/s, T = period
then
w = 2π/T
so
T = 2π/w = 1.8s

Since one rotation is an angle of 2pi radians we need to calculate
time for one rotation = 2pi(rads)/3.5(rads/sec)
= (4/7)pi(rads)(secs/rads) = (4/7)pi secs
= 1.795.. secs

One rotation has 2pie radians
3.5 rad --> 1 sec
2pie rad --> T sec
T = 2pie*1/3.5 = 1.796 sec

1 radian = 57.2957795 degrees
6.28 radians = 360 degrees
6.28 radians / 3.5 radians per second = 1.79 seconds
