Question

A 2.34×10⁴-kgkg space ship starts its vertical journey from the earth's ground with a constant acceleration. Consider that gg remains constant during the motion. Inside the rocket, a 18.5-NN instrument hangs from a wire that can support a maximum tension of 34.1 NN .

1-Calculate the minimum time for this space ship to reach the sound barrier (330m/s)without breaking the inside wire.

2-Calculate the maximum vertical thrust of the ship's rocket engines under these conditions.

3-How far is the space ship above the earth's surface when it breaks the sound barrier?
