Question

A 125 -kg (including all the contents) rocket has an engine that produces a constant vertical force (the thrust) of 1720 $\mathrm{N}$ . Inside this rocket, a 15.5 -N electrical power supply rests on the floor. (a) Find the acceleration of the rocket. (b) When it has reached an altitude of $120 \mathrm{m},$ how hard does the floor push on the power supply? (Hint: Start with a free-body diagram for the power supply.)

Step 1

Given: Mass of the rocket, $m = 125 \, \text{kg}$ Thrust force of the engine, $F = 1720 \, \text{N}$ Using Newton's second law, $F = ma$, where $F$ is the net force, $m$ is the mass, and $a$ is the acceleration. Therefore, $a = \frac{F}{m} = \frac{1720 \, Show more…
