Calculate kinetic energy when angular velocity equilibrium is reached! 3. Calculate the average power given by the motor from idle until it is reached equilibrium!
In the figure below, two 8.00 kg blocks are connected by a massless string over a pulley of radius 2.90 cm and rotational inertia 8.00 x 10-4 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 0.150 rad in 60.0 ms, and the acceleration of the blocks is constant. T (a) What is the magnitude of the pulley's angular acceleration? rad/s2 (b) What is the magnitude of either block's acceleration? m/s2 (c) What is the string tension T1? N
