You launch a model rocket up into the sky. Right after launch the rocket is accelerating upwards at 10m/s^2. What is the magnitude of the net force in Newtons on the rocket if the rocket has a mass of 0.1 kg?

I am going to let gravity be 9.8m/s squared.

I think force = 0.1 * (19.8) N = 1.98N

(I am not 100% sure)

What I love about physics is the impact of words.
Like 'net'.
I looked at Melody's answer earlier and thought 'Yep', add gravity to the thrust.
Then the word 'net' poked me in the ear.
maybe the gross force is 19.8N and the net force is only the thrust.
That makes it 10N
Melody might well be right!
Cheers, Mark
