Answer :
Final answer:
An 84 kg astronaut exerts a force of 823.44 N on his chair while at rest on the launch pad, calculated using the weight formula W = m × g.
Explanation:
The force an 84 kg astronaut exerts on his chair while sitting at rest on the launch pad is equivalent to his weight. The weight of an object on Earth can be found by using the equation W = m × g, where W is the weight, m is the mass, and g is the acceleration due to gravity (approximately 9.81 m/s² on Earth).
Therefore, the astronaut's weight, and thus the force exerted on the chair, is 84 kg × 9.81 m/s², which equals 823.44 N (newtons).
The 84 kg astronaut exerts a force of 824.04 Newtons on his chair at rest on the launch pad, which is calculated by multiplying his mass by Earth's gravitational acceleration.
The force that an 84 kg astronaut exerts on his chair while sitting at rest on the launch pad can be calculated using the weight formula, which is the gravitational force experienced by an object due to Earth's gravity. The weight can be found by multiplying the mass of the astronaut by the acceleration due to gravity (9.81 [tex]m/s^2[/tex]).
Weight = Mass X Gravitational acceleration
[tex]Weight = 84 \ kg X 9.81 \ m/s^2\\Weight = 824.04 \ N[/tex]
Therefore, the astronaut exerts a force of 824.04 Newtons on his chair due to his weight.
