Question

Please help and explain! I will rate lifesaver if correct! I got part a and b correct, but can not get part c for speed and distance.

A package is dropped from a helicopter that is descending steadily at a speed v0. After t seconds have elapsed, consider the following.

    (a) What is the speed of the package in terms of v0, g, and t?
                                                       
(b) What distance d is it from the helicopter in terms of g and t?

    (c) What are the answers in parts (a) and (b) if the helicopter is rising steadily at the same speed?

A package is dropped from a helicopter that is descending steadily at a speed v0. After t seconds have elapsed, consider the following. What is the speed of the package in terms of v0, g, and t? What distance d is it from the helicopter in terms of g and t? What are the answers in parts (a) and (b) if the helicopter is rising steadily at the same speed?

Explanation / Answer

1)velocity after after t=v=v0 + gt

2)distance=s=v0t + 0.5 g t^2

3) part 1 : 1)velocity after after t=v= -v0 + gt

part2: distance=s= -v0t + 0.5 g t^2
