With a jet engine thrust of 2500 N, the rocket launches vertically upward with an acceleration

With a jet engine thrust of 2500 N, the rocket launches vertically upward with an acceleration of 40 m / s2. What is the mass of the rocket?

The given tasks: F (thrust force of the jet engine) = 2500 N; a (rocket acceleration) = 40 m / s2.

Constants: by condition g (acceleration of gravity) = 10 m / s2.

To determine the mass of a given rocket, we apply the formula: F = m * (a + g), whence m = F / (a + g).

Let’s calculate: m = 2500 / (40 + 10) = 50 kg.

Answer: The given rocket has a mass of 50 kg.
