    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    i just checked the original test that this problem was from, and it said on top that all things are measured in meters, and then proceeded to say "unit" in every problem. pretty dumb if you ask me, and seems completely unnecessary. they did the same thing with declaring time units at the top...

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    i believe its vx/sqrt(3). my calculations go as follows: we have vx, and vy(which are perpendicular to each other), and coming from the point, we have a v vector as well(the velocity as 1 variable), which closes a 30 degree angle with vx. if we connect the end of v to the end of vx, we get a...

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    im sorry, when i said 0, i was just confusing vertical with horizontal(im not from an english speaking country) my guess for the angle with which its travelling would be completely parallel to the ceiling, meaning a difference of 30 degrees from horizontal

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    no, it will move downwards every second by that amount, but the amount with which it will move down is constantly increasing

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    i said ay will be equal to g, meaning the y velocity will increase by g every second.

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    the vertical component starts at zero, and ay is equal to g. if we round g to 9.8, then the vertical acceleration is 9.8 as well

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    i think it should be zero, since if it would be any larger, we would hit the ceiling shortly after

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    the only actually useful thing i managed to figure out was that the distance between p and the ceiling is 6 units horizontally. since this is a problem way above my current physics knowledge, i cant do much to solve it, its just that im very interested in the solution of it, since i find the...

    Calculating Velocity Components and Slope for a Falling Rock in a Tunnel

    all i could accomplish was calculating the distance between P and the ceiling in a horizontal line(6)
