Before going into orbit, an astronaut has a mass of 55 kg. After some days in orbit, a measurement determines that a force of 110 N causes her to move with an acceleration of 1.90 m/s2.

What is her mass now?

mass=force/a=???

To find the mass of the astronaut now, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

We are given the following information:
Initial mass of the astronaut (before going into orbit) = 55 kg
Force acting on the astronaut = 110 N
Acceleration of the astronaut = 1.90 m/s²

Using the formula for Newton's second law of motion:

Force = Mass × Acceleration

We can rearrange the formula to solve for the mass:

Mass = Force / Acceleration

Substitute the given values:

Mass = 110 N / 1.90 m/s²

Now we can calculate the mass:

Mass = 57.89 kg

Therefore, the mass of the astronaut in orbit is approximately 57.89 kg.

To calculate the mass of the astronaut after some days in orbit, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = m * a).

In this problem, we are given the force (110 N) and the acceleration (1.90 m/s^2). We need to find the mass (m).

By rearranging the formula F = m * a, we can solve for the mass:
m = F / a

Substituting the given values, we get:
m = 110 N / 1.90 m/s^2

Now, let's calculate the value:
m = 57.89 kg

Therefore, the astronaut's mass after some days in orbit is approximately 57.89 kg.
