Once combined, the bullet+block system swing upward to a maximum height, h. In doing so, the
kinetic energy of the system (just after colliding) is converted into gravitational potential energy.
In terms of g, VWB, h, mB , and mw write these two energies below:

2. The last step is to combine the results from steps 1 and 3 to find the desired result. Use
these to show that the initial bullet speed can be determined from the maximum swing
height, h (also g, and the masses)-
