An LR circuit contains an ideal 60-V battery, a 42-H inductor having no resistance, a 24- resistor, and a switch S, all in series. Initially, the switch is open and has been open for a very long time. At time t = 0 s, the switch is suddenly closed.
 
  How long after closing the switch will the potential difference across the inductor be 24 V?
  A) 1.8 s B) 2.1 s C) 1.4 s D) 1.6 s E) 1.9 s

Question 2

Two cars are traveling at the same speed and hit the brakes at the same time. Car A decelerates (decreases its velocity) at twice the rate of car B. If car A travels a distance D before stopping, how far does car B travel before stopping?
 
  A) 4D
  B) 2D
  C) D
  D) D/2
