A block with mass m = 12 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4599 N/m after being compressed a distance x1 = 0.45 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.7 m long. For this rough path, the coefficient of friction is μk = 0.41. 1) How much work is done by friction as the block crosses the rough spot? 2) Instead, the spring is only compressed a distance x2 = 0.117 m before being released. How far into the rough path does the block slide before coming to rest? 3) What distance does the spring need to be compressed so that the block will just barely make it past the rough patch when released?

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?
