Find:

(a) The resultant force.
(b) The initial acceleration
(c) After reaching a speed of 2390ms(-1) after 150seconds, the average acceleration.

## The Attempt at a Solution

I'd really appreciate someone to provide some help with this, I'm quite stuck :(

Thanks :)

What other forces are acting on the rocket?

Gravity.

So why are you having trouble calculating the resultant force? Did you even try the problem... Next time make an attempt at the solution otherwise you're not going to learn anything.

Jegues,

Of course I attempted it, but I do not understand it. Hence why I am asking for assistance.

Thank you.

If you attempted it and are having troubles, show us your work.
