Weight w are fired from a giant cannon made by a shooting club. In early tests of the cannon, pointed straight up, the people want to shoot a projectile to an altitude of 1.5RE, where RE is the radius of the earth. Dismiss the effects of air resistance and the rotation of the earth. (Note: g = GME/RE2, where G is Newton’s gravitational constant, ME is the mass of the earth and RE is the radius of the earth.) What must the muzzle speed of the projectile be for it to get this high? What is the speed of the projectile when it returns to the surface of the earth (just before hitting the ground)?
