How do I go about solving this problem? No diagram is given, so it's a little hard-to-picture in my head, so I drew a basic diagram but it hasn't really helped.(adsbygoogle = window.adsbygoogle || []).push({});

I use a ballistic pendulum. Large block of wood has a mass M2 = 3.000 kg, and the bullet has a mass of m1 = 25 g. In this problem the bullet completely penetrates the wood and emerges with a speed of vf = 40.0 m/s. The wood, as part of a pendulum, swings up to a maximum height of h = 4.0 cm.

Determine the speed of the block of wood after the bullet has passed through it, and the initial speed of the bullet.

Much thanks
