A 22.0-kg mirror with a surface area of 1.0 m2 and a 98 reflectivity is bombarded by light of average intensity 770.0 W/m2 at an angle of 30.0 to the normal of its surface.
 
  If the light has a duration of how much does the velocity of the mirror change during that time? (c = 3.00  108 m/s, 0 = 4  10-7 T  m/A, 0 = 8.85  10-12 C2/N  m2)
  A) 120 nm/s
  B) 4.2 nm/s
  C) 3.6 nm/s
  D) 2.1 nm/s

When a 45-kg person steps on a scale in an elevator, the scale reads a steady 410 N. Which of the following statements must be true? (There could be more than one correct choice.)
 
  A) The elevator is accelerating upward at a constant rate.
  B) The elevator is accelerating downward at a constant rate.
  C) The elevator is moving upward at a constant rate.
