The 1-meter long, 10-kg slender rod is released from rest when it is completely horizontal. The sliders move along frictionless guides and the spring attached to end A has a constant of k = 3 kN/m. If the spring is compressed by 300 mm when the rod is horizontal, find the angular velocity of the rod and the velocity of end A when the rod is at the position shown.
The 1-kg slender bar has a length of L = 1 m and released from rest in the horizontal position 1 and falls to position 2. What is the velocity of
the mass center of the bar when it is in position 2?.

The ballistic pendulum is a simple device to measure projectile velocity v by observing the maximum angle e to which the box of sand
with embedded projectile swings. Calculate the angle e if the 2.7-oz projectile is fired horizontally into the suspended 59-lb box of
sand with a velocity v = 2150 ft/sec. Also find the percentage n of energy lost during impact.
