    High school physics problem involving a spring slingshot

    Thanks Brian! I am at a loss as to how I would do that, though. As far as I know I need to know how much the spring is stretched to determine the work of the spring before release, but the stretch of the spring is one of my variables.

    High school physics problem involving a spring slingshot

    Homework Statement For a grade 12 physics project we have to stretch a spring along an inclined plane and then let go so that it hits a target. I know the mass of the spring, the angle of the incline, the height of the incline (how high the front of the spring would be off the ground before...

    High school circular motion problem

    Alright, thanks! Sorry it took so long for me to reply. This is the free body diagram I came up with. Am I on the right track?

    High school circular motion problem

    This was very helpful! I understand what you are saying. However, one thing is that my teacher has told the class to not use the term "centripetal" or "centrifugal" forces, saying that they are fictitious forces, and to instead say the force that is causing this kind of motion (for example, when...

    Schools Upon graduating high school, how long will it take to get a PhD in physics?

    I am in my last year of high school and I want to get a PhD in theoretical physics. I'd like to focus on quantum mechanics. There is a lot of information I am missing and I am not really educated on this topic. I think it is best that I learn a bit now. One big thing on my mind is, how long will...

    High school circular motion problem

    I assume there would be a normal force acting on the person leaning against the wall, and I think that would be perpendicular to the slope. There is also the force of gravity pulling the person downwards. There is would also be friction. As the ride spins, the person is supposed to move upward...

    I doubt this is correct, but this is the free body diagram I came up with.

    High school circular motion problem

    Homework Statement The problem is: An amusement park is replacing it's stand-up roller coaster with a G-Force ride. Riders will enter the ride at the apex and lean against the wall of the ride. The G-force ride will speed up until riders reach height h above the apex. Determine the minimum...
