a parachutist opens his chute at time t=0, while falling vertically at a speed of 50.0 m/s. From the combined effects of gravity and air resistance, he is subject to anupward acceleration of  ay= (40/T)e-t/T  where T=6.8s. Find the parachutist's speed 10s after the chute is opened and the distance fallen during that period of time.
A hot-air balloonist, rising vertically with a constant velocity of magnitude 5.00 m/s, releases a sandbag at an instant when the balloon is 40.0 m above the ground . After the sandbag is released, it is in free fall. (a) Compute the position and velocity of the sandbag at 0.250 s and 1.00 s after its release. (b) How many seconds after its release does the bag strike the ground? (c) With what magnitude of velocity does it strike the ground? (d) What is the greatest height above the ground that the sandbag reaches? (e) Sketch ay-t, vy-t, and y-t graphs for the motion.
A particle moves along the positive x axis with a constant acceleration of 2.70 m/s and over time reaches a final speed of 10.0 m/s. (a) If the particie's initial veiocity was 2.2o? mis, what is its displacement during this time, once it reaches its final speed? (Express your answer in vector form.) (b) What is the distance the particle trevels during this time? (C) If the particle's initial velocity was instead -2.20î mis, what is its displacement during this time? (Express your answer in vector form.) A = (d) What is the total distance it travels given the initial velocity in part (c)7
