**Damon**, Thursday, December 29, 2011 at 7:16pmAc = w^2 r

w = 2 pi radians/1.5 seconds = 4.19 radians/second

Ac = 4.19^2 * .75 = 13.2 m/s^2

Fin = m Ac = 25*13.2 = 329 Newtons

Fup = m g = 25 * 9.81 = 245 Newtons

magnitude of force = sqrt(329^2+245^2)

tangent of direction up from horizontal = 245/329
