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?
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.

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
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
90 seconds*(1 min/60 seconds)*(1 hr/60 minutes)= time in hours.
(17,000km/hr-24,000km/hr)/time in hours=correct answer
Report your answer as --- km/hr^2.
Devron is it 280,000 km/hr^2??
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?
You could have just had a typo, but I just want to make sure that you understand.
it's -280,000 km/hr^2
Bingo!!
Best and good luck.

Thank you so much Devron - I really appreciate your help.
i used to come back every year to see if you were still here. I wonder how you are doing.
