This question is typical on some driver’s license exams: a car moving at 45 km/h skids
14 m with locked brakes.
how far will the car skid with locked brakes
at 112.5 km/h? assume that energy loss is
due only to sliding friction.
answer in units of m.

In the first law of thermodynamics, triangle e=q-w, what does q stand for

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.
