Determine the impulse
of the wall on a 10 kg block which is sliding at a velocity of v = 7 m/s,
necessary to stop the block. The coefficient of kinetic friction between
the block and the horizontal plane is 1) 31.2 km 

The accleration of
the block can be obtained before the velocity of the block before it strikes
the wall. Applying the equation v2 = vo2 + 2ac(s  so) yields For the impulse and momentum, we have that So the impulse of the wall on the block necessary to stop the block is I = 31.24 Ns.
