What is the maximum total force exerted on a 71 kg astronaut by her seat during the launch of the Space Shuttle?

You must know the acceleration A of the shuttle

F = m A + m g

To determine the maximum total force exerted on the astronaut by her seat during the launch of the Space Shuttle, we need to consider the concept of acceleration.

1. Recall Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a), represented by the equation F = ma.

2. The acceleration experienced by the astronaut during the launch can be calculated using the formula for acceleration, which is the change in velocity (Δv) divided by the time (Δt), represented by the equation a = Δv/Δt.

3. The change in velocity can be determined by subtracting the initial velocity (v₀) from the final velocity (v), expressed as Δv = v - v₀. The initial velocity of the Space Shuttle during launch is typically zero, as it starts from rest.

4. The time interval of the launch can be obtained from the data or context of the problem.

5. Once the acceleration is calculated, we can use the formula F = ma to determine the maximum total force exerted on the astronaut.

Let's assume the acceleration during the launch is 3g, where g is the acceleration due to gravity (approximately 9.8 m/s²). Now, we can calculate the maximum total force exerted on the astronaut by her seat.

F = ma
F = (71 kg)(3g)
F = (71 kg)(3)(9.8 m/s²)
F ≈ 2,047.4 N

Therefore, the maximum total force exerted on the 71 kg astronaut by her seat during the launch of the Space Shuttle is approximately 2,047.4 Newtons (N).
