Homework Statement
A 0.028 kg bullet is fired vertically at 165 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
mv + mv = mv + mv
The Attempt at a Solution
m1 = 0.028 kg
v1 = 165 m/s
m2 = 0.15 kg
v2i = 0 m/s
(0.028 kg)(165 m/s) + (0.15 kg)(0 m/s) = (0.178 kg) vf
vf=25.96 m/s
v2=vo2 - 2gy
25.962 = - 2(9.8 m/s2)y
y=693.5m
