A box of mass m = 10.0 kg moving at 0.500 m/s is pushed by a force F = {F} N across a horizontal floor.  The applied force is directed at an angle θ = 60.0⁰ as shown in the drawing.  The coefficients of static and kinetic friction between the box and the floor are μs=0.400 and μk=0.300, respectively.  What is the work done (in Joules) by the force F after moving the box a distance of d = 10.0 m? 

A child of mass 30.0 kg begins from rest and slides down a waterslide without friction, then launches into a pool. What is her speed in meters per second at pt. 2 assuming the height of this point is {h} above the ground?

A 70-year-old woman presents with shortness of breath at rest over the past 3 days. She has found it difficult to walk short distances due to shortness of breath. Additionally, she is experiencing confusion, orthopnea, nocturnal dyspnea, and lightheadedness. She denies cough, fever, chills, diaphoresis, anxiety, chest pain, pleurisy, nausea, abdominal pain, vomiting, diarrhea, rashes, and syncope. On physical examination, the patient is short of breath, requiring numerous pauses during conversation. She is afebrile, but she is tachycardic, diaphoretic, and her extremities are cool. There is a diminished first heart sound, S3 gallop, laterally displaced PMI, bibasilar rales, and dullness to percussion and expiratory wheezing noted. An elevated JVD and 2+ pitting edema of the lower extremities is evident. What mechanism is primarily responsible for her symptoms?
