Apackage 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? (use any variable or symbol stated above as necessary. let down be positive.) (b) what distance d is it from the helicopter in terms of g and t? d = (c) what are the answers in parts (a) and (b) if the helicopter is rising steadily at the same speed? speed distance d =

Part a)

Part b)

Part c)

Part d)

Explanation:

Part a)

As we know that speed of package is same as that of helicopter in horizontal direction

So after time "t" the velocity in x direction will remain constant while in Y direction it will go free fall

So we have

Part b)

Distance from helicopter is same as the distance of free fall

so we will have

Part c)

If helicopter is rising upwards with uniform speed

then final speed of the package after time t is given as

Part d)

distance from helicopter

power out to power in less than 100%

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
