An Atwood machine is constructed using a
hoop with spokes of negligible mass. The
2.1 kg mass of the pulley is concentrated on
its rim, which is a distance 22.1 cm from the
axle. The mass on the right is 1.56 kg and on
the left is 1.93 kg. What is the magnitude of the linear acceler-
ation of the hangingmasses? The acceleration
of gravity is 9.8 m/s2 .
Answer in units of m/s2
