1.
A 5.6 g experimental dart is fired into a block
of wood with a mass of 24.3 g. The wood
block is initially at rest on a 2.5 m tall post.
After the collision, the wood block and dart
land 2.7 m from the base of the post.
Find the initial speed of the dart. Answer
in units of m/s.
2.
Equations I used were: delta Y equation, Velocity equation, and the momentum formula.
3.
I solved for time and got .714 seconds. Then I found Velocity=3.78. Then I get lost and don't know what to do next.
