Question
A meter stick of mass 200 grams is balanced on a pivot in the middle of the stick, so that there is no net torque. A mouse of mass 40 grams then jumps onto one end of the stick and holds on. stick_mouse (A) Find the inertia I of the system, about the pivot point. Treat the mouse as a "point mass." kg m2. (B) Find the angular acceleration ? of the stick just after the mouse jumps on. rad/s2. (C) Find the maximum velocity of the mouse. This will happen when he is at the lowest point in his path of motion. m/s
