[SOLVED] Initial Speed formula
A bullet of mass m = 0.01 kg is fired into a ballistic pendulum of mass M = 2.0 kg as shown in Figure 1. The bullet remains in the block after the collision and the whole system rises to a maximum height of h = 8 cm. What is the bullet’s initial speed?
I'm really stumped with what equation to apply to this problem. I want to work it out on my own but I just need help with the what equation to apply.
I've tried the formulas for initial speed.
