1. The problem statement, all variables and given/known data A 590 kg rocket is at rest on the launch pad. What upward thrust force is needed to accelerate the rocket uniformly to an upward speed of 28 m/s in 3.3 s? 2. Relevant equations V = Vi + at F = ma 3. The attempt at a solution I'm just confused about what "thrust force" actually means. Is this the same as normal force? When I solve for a using the first equation, a = 8.485. Using the next equation, I get that F = 5006 N. Is this the upward force? Or do I need to solve for gravitational force (F=mg=5782) and then add 5006 to 5782 and get a total of 10,788 N? If you could please clarify this for me that would be great! Thanks!
