My problem is as follow!(adsbygoogle = window.adsbygoogle || []).push({});

A 45kg dog that is leached, starts to run and the line is all out when he have reach the speed of 20 m/s. The owner will experience a tweak. How do you approximate, this tweak?

My thinking is that it depend on how fast the deceleration are, according to this formula f=ma. But don’t know how to do that approximation I mean does it take 1 sec or two sec; am I missing something?

Then you can think in forum of energy (m*v^2)/2, but I don’t know were to go from there.

I am grateful for any tips!

Kindly Paul-Martin
