You throw a 50.0g blob of clay directly at the wall with an initial velocity of -5.00 m/s i. the clay sticks to the wall, and the collision takes about 20.0 ms (2.00 x 10^-2 s). a) what is the change in momentum for the blob of clay?

0.25 kg-m/s

Explanation:

Given

mass of blob

initial velocity

time of collision

we know Impulse is equal to change in momentum

initial momentum

Final momentum

as final velocity is zero

Impulse

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
