A 0.25 mass is located on the outer edge of a wheel of radius 0.75 m that is turning at a rate of 2 revs/s. Determine the following:
1) The period of the mass
2) The angular speed of the mass in rad/s
c) The tangential speed of the mass
d) The centripetal acceleration of the mass
e) The centripetal force acting on the mass
Any help would be great!!!

I will be happy to check your work.
