In a riveting and apparently infuriating game of croquet, Pierre and Regnault launch their identical croquet balls, which have masses of 0.45 kg each, at each other instead of the wickets. Pierre fires his north at a speed of 5 m/s, and Regnault sends his south at a speed of 6 m/s. The balls collide midair, sending Regnault’s ball directly east at a speed of 4 m/s. In what direction does Pierre’s ball go after the collision? 

The nurse is reviewing the laboratory and diagnostic test findings of a client diagnosed with syndrome of inappropriate antidiuretic hormone secretion (SIADH).  Which of the following would the nurse not expect to find?

The restoring force a bow provides to an arrow as it is pulled back can be modeled as a spring force. The great archer Gila “nocks” an 18-g arrow by pulling it back a distance of 45 cm. Gila fires the arrow horizontally from a small cliff with a height of 12 m, and when the arrow reaches the bottom, it has a speed of 63 m/s. What is the effective spring constant of the bow as Gila nocks the arrow?

A group of local troublemakers send a 600 kg cart crashing into an innocent cabbage stand at a speed of 16 m/s. If the average force on the wagon during the collision is 8500 N, how long does it take for the cart to stop?

As a contact tracer, you have identified several individuals that have come in contact with a know person who has COVID-19. You contact several individuals and follow up with them throughout a 14 day period. None of the individuals you have spoke to so far have any signs associated with COVID-19, so you suspect that they might be asymptomatic. How might an asymptomatic carrier of the coronavirus (SARS-COV-2) interfere with the application of Robert Koch’s postulates? As part of your response, include the Koch’s Postulates.
