    Projectile Motion: How to Calculate Velocity and Position Over Time

    I have the mass of the object, let's say 1kg. So I know the vertical and horizontal accelerations... but I don't know how to get from that to velocity.

    Projectile Motion: How to Calculate Velocity and Position Over Time

    This is just for fun but I have a projectile launched at 35 degrees with a force of 25 N. I know cos35*25N gives me horizontal force of 20.5 N and sin35*25N gives me vertical force of 14.3 N I've got my kinematics but it's been 3 quarters since I've done this so my question is: How...

    Traveling Waves and a Question about Functions

    The kinds of problems that are confusing me at the moment are asking things like how long does it take a portion of the string (or whatever medium) to move between displacement A and displacement B for y(x,t) = ymax * Sin (kx + wt + phi). phi being the phase. So that means they are...

    Traveling Waves and a Question about Functions

    The photograph idea helps considerably with understanding what the shape of the function actually means. So let's see, the kinds of problems that are confusing me at the moment are asking things like how long does it take a portion of the string (or whatever medium) to move between displacement...

    Traveling Waves and a Question about Functions

    Right, I gathered that rhs y is a constant, it should be ymax, the maximum displacement caused by the wave and also the waves amplitude. I guess what I'm having difficulty understanding is how to understand the behavior of a function with two variables (x and t). My normal method is to graph...

    Traveling Waves and a Question about Functions

    I tried to post this in the right spot but if it isn't, feel free to move it and let me know what to do next time. This isn't really a homework question. I'm having trouble understanding the equation y(x,t)=ysin(kx - wt) that describes the displacement caused by a traveling wave, where y is...

    Traveling Waves and a Question about Functions

    I tried to post this in the right spot but if it isn't, feel free to move it and let me know what to do next time. Edit: (Woops! This should be in the calculus physics section! Sorry!) This isn't really a homework question. I'm having trouble understanding the equation y(x,t)=ysin(kx - wt)...
