Question

.060 ball moving @ 2.5 m/s to the right collides with a .090 ball @ rest. How are initial and final momenta related? What are speeds and directions of each after collision? Impulse imparted during collision?

Answer 1

pi=.060*2.5=
pf=(.090+.060)*vf
pf=pi => vf=


I=(.090+.060)*vf-0.60*2.5= (not sure)
