Question

A 0.18-  kg block on a wooden table is given a sharp blow with a hammer. The block then slides across the table to a stop.  The coefficient of friction between the block and table is 0.32. The hammer's force on the block as a function of time is well approximated by an isosceles triangle with it's base on the horizontal time axis. The length of the base is 0.0066  s and the maximum force is 43.0  N. How far does the block go?  Use a graphical technique.

Please show all work and why you used the equations you used

Explanation / Answer

The area of the "force triangle" is the impulse on the block,
A =
