Question

to and fixed to . A small sphere attachod to a light rigid rod rotates about an axis perpe the other end of the rod Relative to the positive direction of the axis of rotation, the angular positions of the sphere are positive, its angular velocity is positive, and its angular acceleration is negative. The sphere is a) rotating clockwise and speeding up b) rotating elockwise and slowing down c) rotating d) rotating counterclockwise and slowing down e) first rotating clockwise and then counterclockwise. se and spoeding up A solid eylinder shown rotates about a fixed axis per the page at the point labeled P at an angular velocity o. The object has mass M and radius R. Determine the kinetic energy of this objoct Take la MR 2. to Solid Cylinder e) MR 3. A particle locatod at the position vectox)(m) has force P-6 2) 00) acting on it. The torque about the origin is a) lk (Nm) b) S (N m) c) LE (Nm) )-S (N m) e) (2-3)(Nm)
