Question

A rocket launched from an initial height of 1.2 m reaches a height of 14 m then falls to the ground. a. Draw a vector diagram of the rocket's movement. b . How far away vertically does the rocket land from its initial position ? . Find the resultant displacement mathematically .

Answer 1

(a) The vector diagram of the rocket will consist of the weight (W), upward thrust force (F) and the air resistance (Fs).

(b) The vertical distance traveled by the rocket from its initial position is 1.2 m.

(c) The resultant displacement of the rocket is 12.8 m.

How to draw the vector of the rocket displacement?

(a) The vector diagram of the rocket will consist of the weight of the rocket acting downwards, upward thrust force of the rocket and the air resistance opposing its motion.

(b) The vertical distance traveled by the rocket from its initial position is calculated as follows;

vertical distance = 1.2 m

(c) The resultant displacement of the rocket is calculated as follows;

displacement = final position - initial position

displacement = 14 m - 1.2 m

displacement = 12.8 m
