A parachutist bails out and freely falls 59.7 m. Then the parachute opens and thereafter she decelerates at 1.60 m/s2. She reaches the ground with a speed of 3.41 m/s. What is her average speed (in m/s) for the fall?

Block A has a mass of 4.11 kg and block B has a mass of 5.1 kg. The blocks are connected by a string of negligible mass and are free to slide on a horizontal, frictionless surface. A force vectorA=(11.1 N)i is applied to block A and a force vectorB=(24.6...
