Homework Statement
Block 1 (0.5 kg) travels with an initial velocity of [ 60i ] + [ 40j ] m/s and then collides with block 2 (0.5 kg) traveling with an initial velocity of [ -60i ] + [ -60j ] m/s.
After the collision, block 1 has a final momentum of [ 0i ] + [ 5j ] kg*m/s. Assume that no external forces are present and therefore the momentum for the system of blocks is conserved.
What is the total initial momentum of the system of blocks?
i + j kg*m/s
What is the change in momentum for block 1?
i + j kg*m/s
What is the change in momentum for block 2?
i + j kg*m/s
What is the final momentum of block 2?
i + j kg*m/s

p=mv
The Attempt at a Solution
I tried P1x= -10-40*.5
p1y=0
p2x=2.5-40*.5
where i got the final velocity from m1v1 +m2v2 + etc. =m1v1 +m2v2 + etc.
