Question

What acceleration A should jet engines bring to a spaceship in the outer space for an astronaut to have weight p=700N. If an astronaut mass is 75kg

Answer 1

$ma=p=700$ ⇔  $a= \frac{p}{m} = \frac{700}{75} =9,33$

Answer 2

To determine the acceleration required for an astronaut to have a weight of 700 N in outer space, we can use Newton's second law of motion:

F = m * a

Where: F is the force (weight) exerted on the astronaut (700 N) m is the mass of the astronaut (75 kg) a is the acceleration we want to find

Rearranging the equation, we have:

a = F / m

Substituting the given values:

a = 700 N / 75 kg

Calculating the value:

a ≈ 9.33 m/s²

Therefore, the jet engines should bring a constant acceleration of approximately 9.33 m/s² for the astronaut to experience a weight of 700 N in outer space.
