Question

A $25,000-\mathrm{kg}$ rocket blasts off vertically from the earth's sur- face with a constant acceleration. During the motion considered in the problem, assume that $g$ remains constant (see Chapter 12 ) Inside the rocket, a $15.0-\mathrm{N}$ instrument hangs from a wire that can support a maximum tension of 35.0 $\mathrm{N}$ . (a) Find the minimum time for this rocket to reach the sound barrier $(330 \mathrm{m} / \mathrm{s})$ without breaking the inside wire and the maximum vertical thrust of the rocket engines under these conditions. (b) How far is the rocket above the earth's surface when it breaks the sound barrier?
