 Find the slope of the line tangent to the graph of contraction velocity at a load of 2 kg. Give units.

please explain tangent lines and how to find them

anonymous · Answer

A tangent line is a line that touches the curve at only one point (for the most part), yet does not cross the curve.

anonymous · Answer

The tangent line would look like this. Notice that it intercepts the curve at x=2

anonymous · Answer

So in other words, the tangent line has the same slope as the curve at x=2

anonymous · Answer

Does that help?

anonymous · Answer

yea helps alot thanks

anonymous · Answer

but what do you think the slope would be

anonymous · Answer

Just by looking at the graph, I'd guess about -1/2.
