A package is dropped at time t = 0 from a helicopter that is descending steadily at a speed...
Homework Answers
(a) we know that
vf = vi + a t
If +y is upward then we have
vh = -vi
a = - g
t = t
vf = vp
So that vp = - vi - gt
|vp| = (vi + gt) m/s
(b) Displacement of packet yp = -vi * t - 0.5 gt^2
Displacement of helicopter yh = vh * t = - vi * t
Therefore d = -vi * t - 0.5 gt^2 - [- vi * t ]
= - 0.5 gt^2
negative sign indicates packet is below the helicopter.
