(a) At a certain instant, a particle-like object is acted on by a force F = (4.70 N )î – (1.20 N )ƒ + (8.00 N )k while the object's velocity is v = - (3.30 m/s )i + (3.10 m/s )k. What is the instantaneous rate at which the force does work on the object? (b) At some other time, the velocity consists of only a y component. If the force is unchanged, and the instantaneous power is -17.0 W, what is the velocity of the object just then? (Give your answer without a unit vector.) (a) Number Units (b) Number Units
spherical R a vertical axis on frictionless bearings (see the figure above). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I and radius r, and is attached to a small object of mass m. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen a distance d after being released from rest? Use energy considerations. NOTE: Eoncono au ome of and
A 10.0-kg bob is attached to a rod whose length is 10.0 m. The right end of the rod is fixed, and the bob is released from rest. a) Determine the speed of the bob when it is below the pivot point (vertical angle is zero). b) Determine the tension in the rod when the bob is below the pivot point. hint: to determine the speed of the bob when it is below the pivot point, you will need to use Calculus.
