    A golf ball being hit on the moon vs Earth

    I am just not sure if I did this properly. My professor hasn't really gone over when to use the range equation but I would assume range would equal the distance traveled therefore can be used for this problem. If not the how would I go about solving this? I did 1/6*9.8=1.63 for g on the moon...

    Rocket engine question.

    21.1*50=1055 1055m/s is the velocity when the engine fails. I don’t know what the time should be in the second equation.

    Magnitude of an electric field

    1. Homework Statement An electron is projected with an initial speed v0 = 4.65×106 m/s into the uniform field between the parallel plates in (Figure 1). The direction of the field is vertically downward, and the field is zero except in the space between the two plates. The electron enters the...

    Courses Is it okay to not understand the calculus in intro physics?

    I don't understand a good portion of the non-algebraic math behind much of the physics in my first semester college class. I understand everything with algebra, and can solve all problems, but I don't understand the relationships with vector cross/dot products, calculus derivations, DE, etc...

    Courses Is there much difference between algebra- and calculus-based physics

    I’m in an honors calc-based physics 1 course at my college and I can’t audibly understand my professor. I tried looking for tutorials online, but I have no idea if what I’m looking at is calc-based physics or alg-based physics, and I don’t want to learn the wrong methods. Is there a difference...

    Struggling with a free-fall question

    1. Homework Statement Two stones are thrown simultaneously, one straight upward from the base of a cliff and the other straight downward from the top of the cliff. The height of the cliff is 6.00m. The stones are thrown with the same speed of 9.0m/s. Find the location (above the base of the...

    I'm having a comprehension issue with a 2-D motion problem.

    1. Problem Statement A 2 kilogram block rests at the edge of a platform that is 10 meters above level ground. The block is launched horizontally from the edge of the platform with an initial speed of 3 meters per second. Air resistance is negligible. The time it will take for the block to reach...

    I am lost; projectile motion

    1. Homework Statement find the initial velocity if a ball is shot at 0 degrees, goes 99.3 cm forward at a height of 25.5cm then use this velocity to determine the x distance if shot at 60 degrees at a height of 114cm part 1 Vinitial: ? delta x: 99.3cm delta y: 25.5cm degree: 0 Part 2...

    Algebra Books that mix modern physics with algebra and geometry

    Hi I'm an advanced undergraduate physics student and I'm currently searching books for my career project. The topic I selected is titled: Algebra and geometry in modern physics. So I'm currently looking for books that cover modern aspects of physics in a more mathematical approx. In specific I'm...

    Classical Challenging Algebra based physics

    Hello, I'm looking for an algebra based physics book with challenging problems. The reasons is because I'm preparing for an exam (in two weeks time) which will have algebra based physics. Here are the topics: 1. Kinematics 2. Dynamics (Newton's laws, Momentum , Work & Energy) 3. Gravitation 4...

    Equations of Kinematics in 2-D/Projectile Motion

    1. Homework Statement A tennis ball is struck such that it leaves the racket horizontally with a speed of 28.0 m/s. The ball hits the court at a horizontal distance of 19.6 m from the racket. What is the height of the tennis ball when it leaves the racket? 2. Homework Equations v = vo + at x...
