A cargo helicopter, descending steadily at a speed of 3.8 m/s, releases a small package. Let upward be the positive direction for this problem. (a) If the package is 94 m above the ground when it is dropped, how long does it take for the package to reach the ground? (a) What is the initial velocity of the package? How does it compare to that of the helicopter? What is its sign? What about the magnitude and sign of the acceleration? s (b) What is its velocity just before it lands? (Indicate the direction with the sign of your answer.)

A car drives straight off of a horizontal cliff with a speed of 45.3 m/s. If it is in the air for 4.43 s, how far from the base of the cliff does the car land? And what is the height of the cliff?
Please don't provide handwritten solution... A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to the victim with an initial velocity of 1.50 m/s and observes that it takes 2.3 s to reach the water. How high (in m) above the water was the preserver released? Note that the downdraft of the helicopter reduces the effects of air resistance on the falling life preserver, so that an acceleration equal to that of gravity is reasonable. ____m
