Решение задачи по физике раздел 47 пункт 91 механика

91. A flywheel as a solid disk, the moment of inertia J = 1.5 kg • m2 rotating when braking ravnozamedlenno for time t = 1 min reduced the frequency of their rotation with n0 = 240 rev / min to n1 = 120 rev / min. To determine: 1) the angular acceleration ε flywheel; 2) The moment M of braking forces; 3) A brake job
