# Adrian Ayala

Physics teacher | Experienced educator in USA

I hold a degree in Physics from The American College of Financial Services. With a passion for unraveling the mysteries of the universe, I bring a deep understanding of physics concepts to my teaching. From classical mechanics to quantum theory, I strive to make complex topics accessible and engaging for my students. With a dedication to fostering a supportive learning environment, I aim to empower students to excel in their academic pursuits and develop a lifelong love for physics. Let's explore the wonders of the universe together.

## Questions

An object is at rest at #(2 ,8 ,6 )# and constantly accelerates at a rate of #5/3 m/s^2# as it moves to point B. If point B is at #(3 ,2 ,7 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.

An object is at rest at #(8 ,2 ,5 )# and constantly accelerates at a rate of #7/4 m/s^2# as it moves to point B. If point B is at #(6 ,5 ,1 )#, how long will it take for the object to reach point B? Assume that all coordinates are in meters.
