Question

2.

A loaded Boeing 747 jumbo jet has a mass of 200,000 kg. What net force is required to give the plane an

acceleration of 3. 5 m/s down the runway for takeoffs?

Answer 1

We can use Newton's second law of motion to calculate the net force required to accelerate an object. The equation is:

F = ma

Where:

F = net force (N)

m = mass of the object (kg)

a = acceleration (m/s^2)

Given that the mass of the loaded Boeing 747 is 200,000 kg and the desired acceleration is 3.5 m/s^2. We can substitute these values into the equation:

F = 200,000 kg * 3.5 m/s^2 = 700,000 N

Therefore, the net force required to give the plane an acceleration of 3.5 m/s^2 is 700,000 N. This is a significant force, which is required to overcome the inertia of the massive object, and to move it down the runway.
