A cargo helicopter, descending steadily at a speed of 3.2 m/s, releases a small package. Let upward be the positive direction for this problem. (a) If the package is 39 m above the ground when it is dropped, how long (in s) does it take for the package to reach the ground? (b) What is its velocity (in m/s) just before it lands? (Indicate the direction with the sign of your answer.) A cargo helicopter, descending steadily at a speed of 3.2 m/s, releases a small package. Let upward be the positive direction for this problem.
