Title: How can I find velocity and initial position given just position and time? Post by: dattallmofo_ on Dec 5, 2012 Given the equation x=vt+x0, and just position and time, how can I find velocity and initial position? My professor showed us something finding the solutions with an excel graph, but I couldn't understand how he did it, so if you could explain that too it'd be very helpful! Thanks!

Title: How can I find velocity and initial position given just position and time? Post by: firebird39 on Dec 5, 2012 The equation describes an object moving at a steady velocity v, and with a starting position (when t=0) of x0.
For example, suppose the equation is (with x in metres and t in seconds): x = 5t + 20 then the initial position is 20m and the velocity is 5m/s If you drew a graph (x on y-axis ( a bit confusing), t on x-axis) then the gradient would be the velocity (the gradient would be 5 in this example) and the initial position (x0) would be the y-axis intercept (the value of x where the line crosses the y-axis.) I'm not sure if that's what you mean, but I hope it helps. |
