15.4.3. Uniform drive mass m = 30 kg of radius R = 1 m begins to rotate uniformly accelerated from rest with a constant angular acceleration ε = 2 rad / s2. To determine the kinetic energy of the disk at time t = 2 seconds after the start of motion.

Right after the payment you will receive a link to a zip archive with the solution of the problem 15.4.3
(Chapter 3 - Dynamics theme - 15.4: The kinetic energy of a rigid body) of a collection of short Reshebnik problems on the theoretical mechanics Kep OE, JA Viba, OP Grapis, JA Svetinysh et al. Publishing Moscow / Graduate School / 1989, 2009, 2012.
This task is completed in the word format.
After checking the solutions I would be very grateful if you leave a positive review.
