Compute the initial upward acceleration of a rocket of mass 1.2 multiplied by [tex] 10^4 [/tex] kg if the initial upward force produced by its engine (the thrust) is 2.7 multiplied by [tex] 10^5 [/tex] N. Do not neglect the gravitational force on the rocket.

2. Relevant equations

F = ma

3. The attempt at a solution

I tried doing [tex] \frac{9.8(Thrust - mass)}{mass} = a [/tex]

I get a = 210.7 m/s^2

but thats wrong.

Can anybody tell me what I'm doing wrong?
