You can spot the correct choice just by looking at their units.
Frequency has units of "per second".
a). and b). are distances, so that can't be it.
d). is time, so that can't be it.
c). is a number per second.
If there's a correct6 answer anywhere on this list,
then it has to be c).
Answer:
20.2 seconds
Explanation:
The airplane (and therefore the crate) initially has no vertical velocity, so v₀ = 0 m/s.
The crate is in free fall, so a = -9.8 m/s².
The crate falls downward, so Δx = -2000 m.
Find: t, the time it takes for the crate to land.
Δx = v₀ t + ½ at²
-2000 m = (0 m/s) t + ½ (-9.8 m/s²) t²
t = 20.2 s
It takes 20.2 seconds for the crate to land.
4395g = 4.395 . divide it by 1000
