    What Is the Required Thrust Force to Launch a 590 kg Rocket?

    (I'm using negative to indicate the downward direction and x=upward force) -5782 + x = 5006 x = 10,788 N Is this the final answer? (and also thank you for taking the time to explain to me what net/thrust/normal force all mean)

    What Is the Required Thrust Force to Launch a 590 kg Rocket?

    The thrust force? But my question is how do i calculate that? I have only learned formulas for frictional, gravitational, and normal force. I don't understand "thrust" force. Can't I just use F=ma? If not, what do I do?

    What Is the Required Thrust Force to Launch a 590 kg Rocket?

    So I drew the FBD of the rocket and I have one arrow going upward for the normal force and one arrow going downward for the gravitational force. I haven't learned any other forces besides frictional force, so I am still not quite understanding exactly what you mean by the rocket motor producing...

    What Is the Required Thrust Force to Launch a 590 kg Rocket?

    Homework Statement 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? Homework Equations V = Vi + at F = ma The Attempt at a Solution I'm just confused about what "thrust force" actually...

    Forces, elevator, acceleration -- I have the answer, just explain it....

    Homework Statement When a 45-kg person steps on a scale in an elevator, the scale reads a steady 480 N. Which of the following statements must be true? There could be more than one correct choice. a) The elevator is accelerating upward at a constant rate b) The elevator is moving downward at a...
