Aballistic pendulum can be used to measure the speed of a projectile, such as a bullet. the ballistic pendulum consists of a stationary 2.50- kg block of wood suspended by a wire of negligible mass. a 0.0100- kg bullet is fired into the block, and the block (with the bullet in it) swings to a maximum height of 0.650 m above the initial position (see class note for drawing). find the speed with which the bullet is fired, assuming that air resistance is negligible.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
