A particle of mass 1kg is projected at an angle of theta=pi//4 from horizontal with a muzzle velocity of 20 m//s. A long slender rod of mass 5kg and length 30 m is suspended vertically from a point at the same horizontal leves as that of point of projection and at a distance of 60m from the projection point. The rod can rotate freely. If collision occurs, it is perfectly plastic. (g=10m//s^(2)) If projectile is fired horizontally, it will |
