- Homework Statement:
- How much force is required to lift a 10 kg box such that it is accelerated from rest to a velocity of 5 m/s within 1 second?

- Relevant Equations:
- F = ma ; v/t = a; Kinematics; Force Equations

I realize that there is a downward force of gravity weighing the object toward earth’s surface, equaling F = mg (downward). The upward force would have to be something at least as much as the downward force in order to lift the object up ”such that it is accelerated from rest to a velocity of 5 m/s within 1 second” as stated in the question stem. The remaining question is how much more Newtons (N) of force is required in order to lift the object up at that acceleration in that amount of time?
