[futuristic]

A 30.0-kg object experiences a drag force due to air resistance with a magnitude proportional to the square of its speed. The object falls with an acceleration of 4.00 m/s2 downward when it is falling downward at 70.0 m/s.
 
  What is its terminal speed?
  A) 172 m/s B) 108 m/s C) 110 m/s D) 157 m/s E) 91.0 m/s

Question 2

The voltage and power ratings of a particular light bulb, which are its normal operating values, are 110 V and 60 W.
 
  Assume the resistance of the filament of the bulb is constant and is independent of operating conditions. If the light bulb is operated with a current that is 50 of the current rating of the bulb, what is the actual power drawn by the bulb?
  A) 15 W B) 10 W C) 30 W D) 20 W E) 25 W
