In summary, The question asks how much force it would take for a person to stop a falling plane and prevent it from crashing. The plane weighs 20,000kg and is moving at 1200 kmh. The person weighs 50kg. To stop the plane, it would need to be decelerated from 1200 kmh to 0.

Homework Statement


A plane is in a freefall heading downwards and is about to crash
how much force does it require for a person to hold the plane from the nose of the plane and level it down so it does not crash.

Masses
-------
Humen 50kg
plane 20,000kg
vi: 1200 km/hr

question i want to know is how much for does it take for a person that weighs that much to stop a falling plane.

Homework Equations





The Attempt at a Solution



i tried to do M x G but apparently it is not correct.

any help would be appreciated thanks.

The plane is moving... You'll need to decelerate it from 1200kmh to 0.

the plane is falling why do i have to decelerate it?

Well, if you don't decelerate it before it reaches the ground, it'll crash onto the ground at 1200 kmh.
 

1. How is force measured?

Force is typically measured using a unit called Newtons (N). This unit is named after the scientist Sir Isaac Newton and is defined as the amount of force required to accelerate a mass of one kilogram by one meter per second squared.

2. What factors affect the amount of force required?

The amount of force required can be affected by a variety of factors, including the mass of the object, the acceleration of the object, and the surface area over which the force is applied. Other factors such as friction, air resistance, and gravity can also play a role in determining the amount of force needed.

3. How do I calculate the amount of force required?

The amount of force required can be calculated using the formula F=ma, where F represents force in Newtons, m represents mass in kilograms, and a represents acceleration in meters per second squared. This formula is known as Newton's Second Law of Motion.

4. Can the amount of force required be negative?

Yes, the amount of force required can be negative if the direction of the force is opposite to the direction of the motion. This is known as a resistive force and can occur in situations such as braking a moving object or pushing against a force of gravity.

5. How does the amount of force required change with distance?

The amount of force required does not necessarily change with distance. However, the work required to exert the force over a distance may increase as the distance increases. This is because work is a measure of the force exerted over a distance, and therefore, the amount of force required to do the same amount of work will increase as the distance increases.
