Projectile Motion

Question

A cargo plane is flying horizontally at an altitude of 11.7 km with a constant speed of 1201 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.

My answer was 48.8397 seconds which was correct

What is the horizontal distance of the crate from the point it fell off to the point where it hits the ground? Answer in km.

How far is the crate from the aircraft when the crate hits the ground, assuming that the plane continues to fly with constant velocity? Answer in units of km.

Answer 1

The part 2 answer is Dx= V*t, which comes out to 16.28km. Remember that 1201km/(3600 seconds) before multiplying by your time answer of 48.8 seconds

Part 3, vertical Dy stays constant! at 1201 km. I can make more videos if you need more explanation :D
