Homework Statement
A 0.030-kg bullet is fired vertically at 200 m/s into a 0.15-kg baseball that is initially at rest. How high does the combined bullet and baseball rise after the collision, assuming the bullet embeds itself in the ball?
Homework Equations
m1v1 + m2v2 = (m1 + m2) v'
The Attempt at a Solution
0.030 kg * 200 m/s + 0.15 kg * 0 m/s = (0.030 kg + 0.15 kg) v' = 6 = 0.18 v'
v' = 33.333 m/s
[tex]\Delta[/tex]p = m(vf-vo) = 0.18 kg (33.333 m/s) = 5.999 = 6 kg * m/s
Ok, this is what I did so far. Even though I know the velocity of the bullet + ball, I don't know how high it went up because I think I need to know the time or acceleration to find x, which is height.
Please help me what to do next.
