Rotational Kintematics...?

Question

a rotating wheel requires 3.00 s to rotate 37.0 revolution. Its angular velocity at the end of the 3.00-s interval is 98.0 rad/s. What is the constant angular acceleration of the wheel?

this seems like it should be easy but i have no idea how to do this without the initial speed.

i know you guys can help

Answer 1

v=at+vo so vo= v-at =98-a3.00
plug this into
and x= vo t +1/2 at^2 and solve for a with x=37
