In the figure, two 9.10 kg blocks are connected by a massless string over a pulley of radius 2.10 cm and rotational inertia 7.40 x 104 kg-m². The string does not slip on the pulley; it is not known whether there is friction between the table and the sliding block; the pulley's axis is frictionless. When this system is released from rest, the pulley turns through 0.900 rad in 170 ms and the acceleration of the blocks is constant. What are (a) the magnitude of the pulley's angular acceleration, (b) the magnitude of either block's acceleration, (c) string tension T₁, and (d) string tension T₂? Assume free-fall acceleration to be equal to 9.81 m/s².

Question
Transcribed Image Text:In the figure, two 9.10 kg blocks are connected by a massless string over a pulley of radius 2.10 cm
and rotational inertia 7.40 × 104 kg-m². The string does not slip on the pulley; it is not known
whether there is friction between the table and the sliding block; the pulley's axis is frictionless.
When this system is released from rest, the pulley turns through 0.900 rad in 170 ms and the
acceleration of the blocks is constant. What are (a) the magnitude of the pulley's angular
acceleration, (b) the magnitude of either block's acceleration, (c) string tension T₁, and (d) string
tension T₂? Assume free-fall acceleration to be equal to 9.81 m/s².
