Two forces act on a 55kg object. One force has magnitude 65 N directed 59 clockwise from the positive x-axis, and the other has a magnitude 35 N at 32 clockwise from the positive y-axis. What is the magnitude of this object's acceleration?
 
  A) 1.5 m/s2 B) 1.7 m/s2 C) 1.1 m/s2 D) 1.3 m/s2

Question 2

The acceleration due to gravity is 10 m/sec2. If an object falls from rest, its instantaneous speed at the end of the fifth second is (neglecting air resistance)
 
  A) 10 m/sec.
  B) 5 m/sec.
  C) 100 m/sec.
  D) 50 m/sec.
  E) impossible to determine from the given information.

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.
