Air resistance (adapted from Putnam Exam, 1939) An object
Chapter 6, Problem 39(choose chapter or problem)
Air resistance (adapted from Putnam Exam, 1939) An object moves in a straight line, acted on by air resistance, which is proportional to its velocity; this means its acceleration is a1t2 = -kv1t2. The velocity of the object decreases from 1000 ft>s to 900 ft>s over a distance of 1200 ft. Approximate the time required for this deceleration to occur. (Exercise 38 may be useful.)
