Amelia Adams
Physics teacher | Tutor for 8 years
With a passion for unraveling the mysteries of the universe, I hold a degree in Physics from Illinois Wesleyan University. I'm dedicated to fostering a deeper understanding of the cosmos through engaging teaching methods. Whether it's classical mechanics or quantum theory, I strive to make complex concepts accessible to all students. My goal is to inspire curiosity and ignite a lifelong love for learning in each individual I teach. Together, let's explore the wonders of the physical world.
Questions
A spring with a constant of #5 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #1 kg# and speed of #9 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
A truck pulls boxes up an incline plane. The truck can exert a maximum force of #3,500 N#. If the plane's incline is #(3 pi )/8 # and the coefficient of friction is #9/4 #, what is the maximum mass that can be pulled up at one time?
An object with a mass of #2 kg# is acted on by two forces. The first is #F_1= < 9 N , 5 N># and the second is #F_2 = < 7 N, -6 N>#. What is the object's rate and direction of acceleration?
