elastic collision help!
A spherical satellite of radius 4.7 m and mass M = 195 kg is originally moving with velocity
v1i = < 2800, 0, 0 > m/s, and is originally rotating with an angular speed w = 2 radians/second, in the direction shown in the diagram. A small piece of space junk of mass m = 4.1 kg is initially moving toward the satellite with velocity v2i = < -2200, 0, 0 > m/s. The space junk hits the edge of the satellite at location C as shown in the diagram, and moves off with a new velocity v2f= < -1200, 490, 0 > m/s. Both before and after the collision, the rotation of the space junk is negligible.
After the collision, what is the final momentum of the satellite?
What is the initial rotational angular momentum of the satellite, around location D (its center of mass)? (Be sure your signs are correct).
im stuck on these two parts. i found out the rest and now stuck.
i used Mv1i + mv2i = Mv1f + mv2f
but got stucked
what should i do? any help would be great!
thanks
