A 260times104- rocket blasts off vertically from the earths, Ask an Expert

Academics

A 2.60×104- rocket blasts off vertically from the earth's surface with a constant acceleration. During the motion considered in the problem, assume that remains constant. Inside the rocket, a 13.1-instrument hangs from a wire that can support a maximum tension of 32.8 . Find the minimum time for this rocket to reach the sound barrier without breaking the inside wire. Find the maximum vertical thrust of the rocket engines under these conditions. How far is the rocket above the earth's surface when it breaks the sound barrier?
