Problem: A uniform rod length with a length of 2 meters and a mass of 12 kg is hung from a pivot at one end. A particle with mass 2.3 kg is thrown at the rod and sticks to it at a point 0.8L below the pivot. At what speed must the particle be thrown so that the maximum angle between the rod and the vertical is 90 degrees?
A projectile is launched straight up at 53 m/s from a height of 86.5 m, at the edge of a sheer cliff. The projectile falls just missing the cliff and hitting the ground below. Discover the time it takes to hit the ground at the base of the cliff.
