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 dont know what to do next.
