(a)

Graph :

Graph of the horizontal distance traveled by the plane :

The airplane travels a miles in one hour.

When the plane reaches to a certain height,

it will maintain a constant velocity.

There is a slight curve at the beginning and end of the

plane because velocity changes.

axis: Distance travel by the plane.

axis: Time taken to reach the destination.

(b)

Graph :

Graph of the altitude of the plane :

There is a change in height at the beginning and ending of the plane.

In the rest of the time, the airplane maintains a same altitude thought

out the journey.

axis: Altitude of the plane.

axis: Time taken to reach the destination.

(c)

Graph :

Graph of the ground speed :

Ground speed is the horizontal speed of an aircraft relative to the ground.

During take off of time the velocity increases, after that it maintains

a constant velocity in the middle and while landing the plane the

velocity decreases.

axis: Ground speed.

axis: Time taken to reach the destination.

(d)

Graph :

Graph of the vertical velocity :

Vertical velocity is the special type of velocity because velocity in the vertical

direction is always affected by the acceleration due to gravity.

During take off the vertical velocity is positive and increases and

it reaches to some height vertical velocity decreases to zero since

the plane is not moving up or down.

axis: Vertical velocity.

axis: Time taken to reach the destination.
