- An object has its center of mass 7.25 cm from the pivot point of a servo. Assuming that the servo has a maximum torque of 1.75 kg - cm (based on a stall torque of 2.5 kg - cm, reduced by 30% to provide a buffer), what is the maximum mass that the object can be to not exceed the 1.75 kg - cm limit? Round your response to the second decimal place (i.e., #.##).Twin skaters approach one another as shown in the figure below and lock hands. (a) Calculate their final angular velocity (in rad/s), given each had an initial speed of 2.70 m/s relative to the ice. Each has a mass of 92.0 kg, and each has a center of mass located 0.890 m from their locked hands. You may approximate their moments of inertia to be that of point masses at this radius. (Enter the magnitude.) (b) Compare the initial kinetic energy and final kinetic energy. Initial kinetic energy is greater than final kinetic energy. Initial kinetic energy is less than final kinetic energy. Initial kinetic energy is the same as final kinetic energy.A 60 kg girl runs through a speed of 10 m/s on a smooth floor and decelerates to a stop in front of a 1m wide door. Determine the torque the girl exerting to the 1m wide door relative to the hinges if she pushes it perpendicularly with a 38N force at a distance d from the hinges.
