A raindrop of mass 57.40 mg (that is milli- gram) falls in quiet air (no wind). Due to the air resistance force, the drop has a maximum velocity called the terminal velocity of magnitude, 17.50 m/s, which is reached high above ground. What would be in N the weight of the rain drop after it reaches terminal velocity and before it reaches ground? Use g = 10 m/s2 and take the upward direction as positive.
