Question

A rocket drifts sideways in outer space from point "a" to point "b" as shown below. The rocket is subject to no outside forces. Starting at position "b", the rocket's engine is turned on and produces a constant thrust (force on the rocket) at right angles to the line "ab". The constant thrust is maintained until the rocket reaches a point "c" in space

1. Which of the paths below best represents the path of the rocket between points "b" and "c" ?

(A) 

(B) 

(C) 

(D)

2. As the rocket moves from the position ''b'' ''c'' its speed is:

(A) constant

(B) continuously increasing

(C) continuously decreasing

(D) increasing for a while and constant thereafter.

3. At point ''c'' the rocket's engine is turned off and the thrust immediately drops to zero. Which of the paths below will the rocket follow beyond point ''c''?

4. Beyond position ''c'' the speed of the rocket is:

(A) constant

(B) continuously increasing

(C) continuously decreasing

(D) increasing for a while and constant thereafter

Answer 1

Correct option: 1 - (B), 2 - (B), 3 - (B), 4 - (A)

Explanation: 

1. 

2. continuously increasing

3. Beyond point C it mill move in straight line, velocity making some only form initial velocity but option.

4. v → content
