Question:
One way to estimate the effective area
of an object is to measure its limiting velocity v∞ falling in air. Explain how this works and find the expression for Aeff as a function of m (the mass of the object), v∞, g, and the density of air. The drag coefficient of a soccer ball (radius 11 cm, mass 0.43 kg) is cd ≈ 0.25. What is its limiting velocity?

I am a dependable person who is known to get through with things always in time. I have been privately tutoring students for the last three years. I started teaching mathematics and physics with a single student from grade 10, then there were two students from the same grade. This was followed by an increase in the number of students significantly from different grades and even college students who were pursuing physics. It was a unique experience every time and all the hard work and guidance were positively reflected in their academics. Each student was different in its own way and challenging at times. But I always gave my best and tried to be creative and interactive enough to help them achieve their targets. I always tried to have a strong bond with students so that they can approach me without any hesitation regarding their queries. Additionally, I am currently teaching around ten secondary school students to help them prepare for college and around 8 college students.
I just believe in leading the students to a proper thinking process in which they can learn and I also learn. This is done by breaking down each lesson into smaller parts with effective examples. Although it does slow down the process, it is quite rewarding in the long run. The tutoring experience has also rewarded me with some transformative personal changes the reason being that I enjoy the process.
