A pendulum is attached to the ceiling by two 1.7 m long strings. The 30 kg block is composed of wood and can be used to measure the initial speed of a 40 g bullet, by finding the height, h, for the resulting block’s swing after the bullet hits. If the strings attached to the block swing to a maximum angle of 4.7° with respect to the vertical, find

A) The potential energy of the system (bullet and block) at the top of the swing.

B) The kinetic energy of the system (bullet and block) immediately after the impact.

C) The velocity of the system (bullet and block) immediately after impact.

D) The initial velocity of the bullet.

E) Is there any energy dissipated to the environment from the bullet/block system during this process? If so how?

1. You shoot a bullet of mass m=0.025 kg into a wood box of mass M=1.7 kg which initially is at rest. After the impact, the wood with embedded bullet moves to the flat top of the hill, and it continues its motion on the top. Initial speed of the bullet before collision is vo=560 m/s. The height of the hill is h=0.3 m. The surface has no friction. At what speed the wooden block moves on the top of...
