Each of the gears a and b has a mass of 675 g and has a radius of gyration of 40 mm, while gear c has a mass of 3.6 kg and a radius of gyration of 100 mm. assume that kinetic friction in the bearings of gears a, b, and c produces couples of constant magnitude 0.15 n·m, 0.15 n·m, and 0.3 n·m, respectively. knowing that the initial angular velocity of gear c is 2000 rpm, determine the time required for the system to come to rest.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
