Homework Statement
A block of mass MB = 0.7 kg hangs from a string wrapped around a hoop that can rotate around its center. The hoop has a mass of MH = 1.3 kg and a radius of R = 0.4 m. The block descends under the influence of gravity. What is the magnitude of the acceleration of the mass in m/s2?
Homework Equations
a = -g(m1-m2)/(m1+m2+.5mp)
where, m1 and m1 = masses of the blocks and mp = mass of the pulley
The Attempt at a Solution
a = -9.8*(0.7)/(.7+.5*1.3) = -5.081 m/s/s
