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

Answer 1

Looking at the previous reply, the slope should be -1/2, which is -0.5. But when I put it in the program online, it's telling me that it's wrong.

Answer 2

This is the tangent line drawn, as shown on a previous question I found.

Answer 3

Nevermind! I figured it out. I just needed to look at the slope of the tangent line, which is 10/-2, or -5 (cm/sec)/kg
