A cargo plane is flying horizontally at an

Question

altitude of 11.2 km with a constant speed of
1260 km/hr when a large crate slides out of
the rear of the plane.
How long does it take the crate to hit
the ground? The acceleration of gravity is
9.81 m/s
2
.
Answer in units of s, please.

Answer 1

h = 11.2km = 11,200 m.

h = 0.5g*t^2 = 11,200
4.9*t^2 = 11,200
t^2 = 2286
Tf = 47.8 s. = Fall time.
