Determine the acceleration of a rocket.

[ehild]

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=?
