2. Once your rocket reaches space, the captain adjusts the speed. Your captain goes from 24,000 km/hr to 17,000 km/hr over 90 seconds. What is your acceleration?

Question

Beginning speed= 17,000km/hr
Ending speed= 24,000 km/hr
Time it took= 90/sec

17000-24000= -7000/90= -77.778km/hr

Should it be ^2?

Please Check

Thank you.

Answer 1

I just need someone to look at this and tell me if it is correct or if I have to convert anything - I am unsure

Answer 2

You have a mistake: the rate is given in units of km/hr, but the time is given in seconds. You have to convert 90seconds to hours before proceeding with the calculations.

90 seconds*(1 min/60 seconds)*(1 hr/60 minutes)= time in hours.

(17,000km/hr-24,000km/hr)/time in hours=correct answer

Answer 3

Report your answer as --- km/hr^2.

Answer 4

Devron is it 280,000 km/hr^2??

Answer 5

Yes and no, since the rocket is decelerating. So, is the final answer 280,000 km/hr^2 or is it - 280,000 km/hr^2?

Answer 6

You could have just had a typo, but I just want to make sure that you understand.

Answer 7

it's -280,000 km/hr^2

Answer 8

Bingo!!

Best and good luck.
