Determine the acceleration of a rocket.

oh my bad then
i thought for calculation purposes only they wanted u to assume tohe rocket fell aft fuel ran out
thanks for clearing up the free fall term for me

How can a rocket change its velocity to zero in no time, without fuel? Even the problem maker can not assume nonsense...

lol i kno
but some of the question i am doing are makin me assume some weird stuff
for basic calculation purposes
sorry.my error
thnx fr the correction again

You are welcome.

So a = 176 ms^2?

No. How did you get it?

Nm I did a calculation error. I now did 0 = 450a + 30a(270) - 1/2 (9.81)(270)^2 = 70 ms-2

 

[ehild]

How can be 0=70 m/s²? Solve the equation for a.

I didn't do the long work in that message, but that's what it came out to I brought the 1/2 x 9.81 x 270 squared to the other side and then divded by 450 + 30 x 270

That is not 70. 1/2 x 9.81 x 270² =357574.5
450 + 30 x 270=8550

357574.5/8550=?
