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 dont know what to do next.
