The cable from drum a turns the double wheel b, which rolls on its hubs without slipping. determine the angular velocity ω and angular acceleration α of drum c for the instant when the angular velocity and angular acceleration of a are 3.9 rad/s and 2.8 rad/s2 respectively, both in the counterclockwise direction. the angular velocity and acceleration of c are positive if counterclockwise, negative if clockwise.

uranium fissions/breaks up giving out energy and neutrons

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

truck y has a greater velocity than truck x.
