Unformatted text preview: at rest. What is the total momentum after the collision? Delta p sub 2 =  delta p sub 1 P sub 2(final) p sub 2 (initial) = (p sub 1 (final) p sub 1 (initial)) P sub 2f + p sub 1f = p sub 1i + p sub 2 i P sub 1 I = (2.0 KG)(1.0 m/s) P sub 2 I = 0 P sub (1+2) final= (3 KG)(v sub f) P I = (2.0 KG)(1.0 m/s) + 0 = (3 KG)(x) Force * delta t is known as impulse Delta p = sigma (force * delta t) Big forc/Short Time VS small forc/long time...
