A. To solve for the time it takes for the package to
strike the ground, all we have to do is to plug in the given values in to the
position equation:
s = −16 t^2 + v0 t + s0
Where,
<span>s = distance of the plane from the ground = - 6000 ft (negative since the package moves from
top to bottom)</span>
t = time for it to strike the ground = unknown
v0 = 0 since the package starts from rest
s0 = 0 since we take the plane as the reference point
Substituting the given values:
- 6000 = -16 t^2 + 0 * t + 0
16 t^2 = 6000
t^2 = 375
t = 19.36 s
B. s = v * t
where v = 600 miles / hr = 0.17 miles / s
s = (0.17 miles / s) * 19.36 s
s = 3.23 miles = 17,054 ft
