A projectile is launched from the surface of the earth. What minimum launch speed is required if the projectile is to rise to a height of the radius of the earth above the surface? Disregard any dissipative effects of the atmosphere.

A uniform meter stick is pivoted to rotate about a horizontal axis through the 25 cm mark on the stick. The stick is released from rest in a horizontal position. The moment of inertia of a uniform rod about an axis perpendicular to the rod and through the center of mass of the rod is given by Determine the magnitude of the initial angular acceleration of the stick.
