A plane flying horizontally at a speed of 50m/s and at an elevation of 160m drops a package of supplies.?

Question

Two seconds later it drops a second package. How far apart will the two packages land on the ground?
A)162m
B)177m
C)67.7m
D)283m

Answer 1

They will land 100 meters apart since the plane is flying at 50 m/s and the time interval between their being dropped is 2 seconds. Their trajectories will be two parallel parabolic segments, 100 m apart.

Answer 2

The altitude of the plane is not relevant, the objects will hit the ground 100 meters apart.

Answer 3

Answer C.
--------------------------------------------------------------------------------------------
The horizontal distance traveled depends only upon the initial horizontal speed i.e., 50 m/s

The second ball reaches the ground after two second, i.e., after the first ball has reached the ground.

In 2 second the horizontal distance traveled by the second ball is 2 x 50 = 100m

Therefore, there is a horizontal displacement of 100 m between the first and second ball.

Thus the maximum distance possible is 100m.

Due to air resistance the actual distance will be less than 100m.

The only answer less than 100 m is 67.7 or C.

Answer 4

None of the above. The answer is obviously 100 meters. The plane's altitude is immaterial.

Answer 5

V=distance/time
x=v(t)
=50(2)
=100 m
