Question

In a graph of v1 vs v2. What does the slope represent?

For a perfectly inelastic collision.

They have the same mass.

x-axis is v1 (velocity 1) and y-axis is v2 (velocity 2).

What does the slope represent? And how do we measure this quantity using mathemtacial formula?

(From physical lab experiment)

Answer #1

As you have not mentioned about what V_{1} and
V_{2} are exactly. But still i am answering on the basis of
what it could be.

The slope in this graph will represent coefficient of restitution.

Coefficient of restitution is defined as ratio of velocity of
seperation(V_{2}) to velocity of approach(V_{1})
when two body collides. Mathematically coefficient of restitution
can be calculated by

For perfectly inelastic collision e = 0.

For any doubt please comment and give an up vote. Thank you.

29) Suppose a group of students performed the Standing Wave
experiment and made a graph of T (Tension) (Y-axis) vs. V2
(velocity squared) (X-axis). They made a linear adjustment and
obtained a slope with a value of 0.043. Calculate the value of the
linear density of the string.

Hooke’s Law Hooke's Law For this lab you need to plot a graph of
Force( y axis) versus elongation (x axis) for a spring. The graph
of force vs elongation for spring should be a straight line
(Hooke's law). From the slope determine the elastic constant, k. If
you are not using Excel, draw your graphs by hand, scan or take a
picture and insert the graph in the lab report. Your graph should
have a title, and the axis...
