Part 1: Ballistic Pendulum Experiment
Using a balance, determine the mass of the ball and basket of the ballistic pendulum. Fire the
ballistic pendulum and measure the maximum height the pendulum reaches. Use the
conservation of energy (initial KE+ initial GPE = final KE + final GPE, KE = 12mv?; GPE = mgh)
to calculate the initial speed of the pendulum after the ball has collided with the pendulum
basket. Next, use the conservation of momentum (total initial p = total final p, p= my) to
determine the initial speed of the ball before it collided with the pendulum basket.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
