An object moves in the xy plane in above figure and experiences a friction force with constant magnitude 3.00N, always acting in the direction opposite the objects velocity. Calculate the work that you must do to slide the object at constant speed against the friction force as the object moves along (a) the purple path O to A followed by a return purple path to O, (b) the purple path O to C followed by a return blue path to O, and (c) the blue path O to C followed by a return blue path to O.

A force with a magnitude of 60 N is applied at an angle theta= 50 to the horizontal to an object initially at rest, displacing it 5 m from its initial location. The object weighs 50 kilograms and there is no friction. After this displacement, the force is no longer applied. Determine the work being done by the force? How fast is the object when the force is removed? When the force is no longer exerted, the item falls down a 10-meter-high cliff. When it reaches the ground, what is its velocity? When it strikes the ground, it slides along the ground, which has a coefficient of kinetic friction of 0.25. How far does it go before coming to a stop?
