So I worked on the problem. Sof far I got...
(400 +100)v = 400v1 + (100(-v2))
vfinal = 3/5 vinitial
not sure, what to do now...how to figure out the if the 'space junk' is going to stay in orbit or collide with earth?
thanks!
thanks for trying though!
I need this in few hours. Please help! I am not sure what i am doing wrong. maybe my equation is wrong? I have no idea.
HELP please!
the answer to this problem is greater than part a. and part a is following.
a) Assuming the uranium nucleus was initially at rest, what is the recoil velocity of the remaining nucleus after decay? Explain the physics.
the answer i got for part (a) is vf = 3/5v ; where v is initial velocity.
HELP! URGENT! momentum!
The nucleus of 238U decays by emitting an alpha particle, 4He. The velocity of the alpha has been measured to be v. The mass of the original nucleus is 238 u (atomic mass units) and the mass of the alpha is 4 u. Do not convert atomic mass units into kilograms.

HELP! very urgent! satellite problem.
A 400 kg satellite is going to collide with a smaller 100 kg satellite traveling in the same
orbit but in the opposite direction. Knowing the construction of the two satellites you expect they will become enmeshed into a single piece of space junk...
