Thanks for your reply!
So for b) would the angular speed would be .4s? c) would it be 0? since it goes from 8 to 8 ?

b) yes
c) no (how much tape would you have to wind round the wheel?)

would i use C=2pir?
c= 2(3.14)(5) = 31.4 cm?

because the diameter of the wheel is 10? so half of it would be the radius of 5?

but the graph shows x going from 10 to 10, so half of that would be 10 ?
