so the graph can't show time, but isn't time a parameter in the position equations for the x and y positions? so if i was given at least 2 or 3 of the variables in the position equation for the horizontal and vertical direction i could find the unknown variable using the position equation that...

Trajectory Graphs?? Homework Statement The trouble I'm having is with determining what information I can get from a trajectory graph and how that information differs from what I can find on a position vs. time graph. Is the acceleration I find just the rate of change in the direction of...

Is it just that because you must use the acceleration and velocity in the x direction to find the x position and the acceleration and velocity in the y direction to find the y position that you should be able to find these values from the trajectory graph even though the slope of the trajectory...

So it is my understanding from my book that the information that we can get from a trajectory graph is the direction of velocity, but not the magnitude of velocity. If the tangent line to a point on a trajectory graph just gives the direction of velocity, why can the trajectory graph still be...

I am allowed to use calculus, what I was saying is that the velocity i find for t=1 is equal to 2.5 m/s and the online graph that they have given to me to plot my results only allows me to plot (1,2) or (1,3), not (1,2.5) like i need

I tried doing that, but on the y axis, which is angular velocity I can only plot whole numbers, and finding the area under the curve from t=0-t=1 gives me an area of 2.5

1. So this is one of my homework problems and I just can't seem to get it, and my attempts are verging on pathetic. I feel like this shouldn't be this hard, maybe I'm just missing something. This is the acceleration vs. time graph...
