Q: A helicopter is ascending vertically with a speed of 2.00 m/s. At a height of 160 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground?
Attempt:
[how long it takes to reach the height]
v=delta d/time
2=160/time
2(time)=160
time=80 seconds
[how long it takes to fall]
v=delta d/time
9.8=160/time
9.8(time)=160
time=16.326
80+16.326
96.3 s (which is wrong.)
