Heyy. Considering you have taken this topic, Can you help me with one more question? If yes then the question is below, If no then thats all sweet aswell.
A rocket moving towards Alpha Centuari at 1000ms^-1 fires its rockets, accelerating backwards at a constant rate for 5 minutes. During this 5 minutes, the rocket moved 240km close to the star. What was the acceleration?
All i know is you have to use the formula: a=final-Initial/time.
