OK, want to see if I am using the use of rad properly here
the answer seems very small. but 35 degrees isn't much for all the rotations.

Answer not in book so hope these are correct..

thanks ahead.

Your answers are correct, but I would give exact values instead:

a) \(\displaystyle \frac{190}{3}\pi\text{ rad}\)

b) \(\displaystyle \frac{7}{2280}\text{ s}\)
