    Finding net force using velocity graph?

    Nevermind. I think it's a = 6? I took the slope = 12 / 2 = 6

    Finding net force using velocity graph?

    I got a= -2 at t = 7. I did F = 2.5 x 2 = 5.0 ...It's still wrong

    Finding net force using velocity graph?

    Finding net force using velocity graph? The figure(Figure 1) shows the velocity graph of a 2.5object as it moves along the x-axis. What is the net force acting on this object at t=7 ? The attempt at a solution Since F=ma, I tried first finding a by dividing 6 m by 7 s. Then I...

    Find the points of discontinuity: f(x) = x + 1 , for x < 1 and 1/x for x ≥ 1?

    Well i tried graphing it...but I STILL DON'T UNDERSTAND

    Find the points of discontinuity: f(x) = x + 1 , for x < 1 and 1/x for x ≥ 1?

    Find the points of discontinuity: f(x) = x + 1 , for x < 1 and 1/x for x ≥ 1? ^ supposed to be a piece-wise function. State whether f is left- or right-continuous at each point of discontinuity. I'm having difficulty figuring this out... please help?
