A 100-newton sack of potatoes falls from an airplane. As velocity of fall increases, air resistance also increases, and when air resistance equals 100 N, the acceleration of the sack is A)zero B)5 m/s² C)10 m/s² D)100 m/s² And the velocity of the sack will be E)0 m/s. F)5 m/s. G)10 m/s. H)100 m/s. I)constant.

Question

Quizplus · Accepted Answer

When air resistance equals the gravitational force acting on the sack (100 N), the net force on the sack becomes zero, leading to zero acceleration. At this point, the sack reaches terminal velocity, meaning its velocity becomes constant.
