The PMHNP is seeing a 9-year-old boy for a routine check for refill medication for his ADHD. The mother and boy state the has been doing OK with the exception of a skin rash and fatigue. Prior to this, the boy has always been in good health. The mother reports symptoms may be a lingering virus from a few weeks ago during which time he had a sore throat and fever that they thought resolved without treatment. Concerned with such a history, the PMHNP auscultates the chest to hear a blowing, holosystolic murmur over the left sternal border. Visual examination does confirm a erythematous rash over the torso and limbs. The PMHNP informs the mother and patient they need to follow up with their primary provider today. The PMHNP suspects which of the following is occurring in the patient’s body?

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. This produces a maximum static friction of 81.6 N and kinetic friction of 61.2 N. What is the work done (in Joules) by the frictional force after the box moved a distance of d = 10.0 m?
