Question

2) (lab manual) A projectile is fired horizontally from a ballistic ‘‘gun’’ (i.e. without the solid pendulum and catcher attached) and strikes a vertical board. The horizontal distance from the ballistic pendulum ‘‘gun’’ release point to the board is 0.85 meters; the vertical distance projectile falls is –2.4 meters. What is the initial speed of the ball as it leaves the ‘‘gun’’? 3) (lab manual) The pendulum is connected so it catches the same projectile fired in the previous question. The mass of the projectile is 0.0610 kg and the mass of the solid pendulum is 0.2143 kg. If the solid pendulum rises h = 0.090 m after the collision, calculate a. the initial speed of the projectile, b. the ideal kinetic energy of the projectile and solid pendulum combination immediately after impact, and c. the gravitational potential energy of the ball and pendulum at the highest position.
