Question

A model airplane with a mass of 0.756 kg is tethered by a wire so that it flies in a circle 29.3 m in radius. The airplane engine provides a net thrust of 0.799 N perpendicular to the tethering wire.

Answer 1

To calculate the force exerted on the airplane by the tractor, you can use Newton's second law of motion, which states that force equals mass multiplied by acceleration.

Step-by-step explanation:

To calculate the force exerted on the airplane by the tractor, we can use Newton's second law of motion, which states that force equals mass multiplied by acceleration. In this case, the force exerted by the tractor on the pavement is given as 1.75 × 10^4 N, and the total resisting forces are 2400 N. The acceleration is given as 0.150 m/s². We can rearrange the formula to solve for mass:

mass = (force - total resisting forces) / acceleration

Substituting the given values, we get:

mass = (1.75 × 10^4 N - 2400 N) / 0.150 m/s²

Simplifying the calculation, we find that the mass of the airplane is approximately 1.09333 × 10^4 kg.
