A hot-air balloonist, rising vertically with a constant speed of 5.00 m/s, released a sandbag at the instant the balloon is 40.0 m above the ground. After it is released,

the sandbag encounters no appreciable air drag. 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 will the bag strike the ground? c) How fast is it moving as it strikes the ground? d) What is the greatest height above the ground that the sandbag reaches? e) Sketch graphs of the bag's acceleration, velocity, and vertical position as functions of time.
