A physics question about forces?

A missile is fired horizontally, acceleration from 250 m/s to 1200 m/s in 9 seconds.

A. what is its average acceleration over this period?

B. If the missile weighs 1080 Newtons, what is the average force applied during these 9.0 seconds?

Can some one please answer this question for me and wite down the steps for me. I have a physics test tomorrow and i dont get this question like how to do it. This is a regular physics corse so please dont make this more difficult for me if u answer in a complactied way thank you god bless

acceleration is simply the change in velocity divided by the time the change took place. so subtract the initial from the final and divide the result by the time it took to get there. That should take care of A.

If the missle weighs 1800 newtons then you need to look at the equation F=mA where F is the force in newtons and m is the mass and A is the acceleration. You calculate the mass of the missile by dividing its weight by 9.8m/s^2. Then you take the mass and multiply it by the average acceleration you just calculated in A and it will give you the necessary force.

Give it a try. It should be easy enough to do those caculations.
