2.6 kg mass
initial velocity of v1 =aˆi,
where a = 5.95 m/s collides with and
sticks to a 1.59 kg mass with an initial velocity
of v1 = bˆj, where b = −4.8 m/s.
Find the final speed of the composite mass.
Answer in units of m/s
Some of the text got garbled, but remember that the momentum of the center of mass for the system stays unchanged.
do a web search for inelastic collisions and you'll find several examples.
