You drop a package from a plane flying at constant speed in a straight line. Without air resistance, the package will. (Hint: think about the velocity along the x direction, think about what type of motion you have along x direction).

A) quickly lag behind the plane while falling.

B) remain vertically under the plane while falling.

C) move ahead of the plane while falling.

D) not fall at all.

Expert Solution

Ans : (B) Remain vertically under the plane while falling.

Explanation:

As the plane is moving in constant speed in a straight line and package was in the plane, the speed of the package will also be the same while it is inside the plane.Now when the package is dropped the horizontal speed of the package also be the same as the speed of the plane due to inertia of motion. So at the moment of release , the package will remain vertically under to plane while falling. So option (B) is correct.

other options are incorrect:

(A) At the moment of release , the speed of the package is same as the speed of plane , so it will not lag behind the plane at the moment of release. So this option is incorrect.

(C) Now , after release the package , there is no horizontal acceleration of the package , and due to gravity , it will fall to the ground , so it will not move ahead of the plane while falling. So this option is incorrect.

(D) Due to gravity the package will fall to the ground so this option is not correct.

Objects that move in a straight line with a constant speed—not speeding up or slowing down—have zero acceleration. We call this kind of motion: Uniform Motion. We can identify uniform motion when the object travels equal distance intervals in equal times. We can identify non-uniform motion, or accelerated motion, when the object travels equal distance intervals in unequal times. Finally, we have two types of non-uniform motion: motion with constant acceleration and motion with a non-constant (or changing) acceleration. Activity...

A plane flying horizontally at an altitude of 5 mi and a speed of 470 mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 7 mi away from the station. For full credit I expect to see a well-labeled picture. Show all work. Round your final answer to the nearest whole number. Do not round intermediate values. Include units of measure in your answer.
