Homework: A steel ball weighting 1 kg is dropped from 793m without any velocity. During the fall, the air resis- tance is equal to v, where v is 1 mg-kv=mv' v(0)=0 the velocity of the ball in meters per second. m=1 a. Compute the limiting velocity. g- b. Find the approximate time it takes for the ball to hit the ground if g= 9.8m/s2. by doing partial fractions and with a help of scientific calculator. solve part a then part b.
