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?
^ 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?
