A 14 kilogram object rests on a table. A 72 newton force is applied to the object, horizontally. If the coefficient of static friction between the object and the table is 0.45, does the object move? True

False

What is a good example of instantaneous speed

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
