Can you find the average acceleration?

is this held in earth where gravity exists? lol, i know its a dumb question, but sometimes during my life, i have done problems like these without the involvement of gravity.

Acceleration is in m/s^2.

So what's Newton's second law?

what i did is...

Fnet = (m*v)/t

Fnet = (.09*80)/3 = 2.4N

What did i do wrong?

Fnet = (m*v)/t

Fnet = (.09*80)/3 = 2.4N

What did i do wrong?

Does it give you a rate at which the mass of the rocket is changing?

hey, i have the same question, but what does w stand for? since m = mass, Ft = force of thrust anf a = acceleration (right)? then what is w?

What force must the rocket thrust counteract in order for the rocket to rise?
