Question

How much force does the astronaut exert on his chair while accelerating straight up at 13 m/s² ?

Express your answer in newtons.

Answer 1

The mass of the astronaut is 70 kg, the force exerted on the chair would be: F = 70 kg * 13 m/s² = 910 N.

Step-by-step explanation:

The force exerted by the astronaut on his chair can be calculated using Newton's second law of motion: F = m * a, where F is the force, m is the mass, and a is the acceleration. In this case, the force exerted by the astronaut on his chair is equal to the product of his mass and the acceleration: F = m * a = (mass of astronaut) * (acceleration).

Given that the acceleration is 13 m/s², we need to know the mass of the astronaut in order to calculate the force. Once we have the mass of the astronaut, we can multiply it by the acceleration to find the force in newtons.

For example, if the mass of the astronaut is 70 kg, the force exerted on the chair would be: F = 70 kg * 13 m/s² = 910 N.
