Aballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. the projectile, of mass m, is fired into a large block (of wood or other material) of mass m, which is suspended like a pendulum. (usually m is somewhat greater than m). as a result of the collision, the pendulum and projectile together swing up to a maximum height h. determine the relationship between the initial horizontal speed of the projectile, v and the maximum height h.

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.
