Question

pls give the solution.... answer without solution will be reported​

Answer 1

Answer:

the answer is :-

a. 7.5 km/ s^-2

Answer 2

Answers :

(i) The average acceleration of the spacecraft, when the motor was firing, is 7.5 km/s² .

(ii) The distance ( or displacement) covered in first 10 seconds after the motor started firing is 1065 km .

Note :

In the equations in the solution various letters have been used for representing the different scalar and vector quantities. I am providing a list for reference.

• v represents final velocity
• u represents initial velocity
• t represents time
• S represents displacement/distance
• a represents acceleration
