A block of mass m = 1 kg slides with velocity v = 6 m/s on a frictionless horizontal surface and collides with a uniform vertical rod and sticks to it as shown. The rod is pivoted about O and swings as a result of the collision making angle ? before momentarily coming to rest. If the rod has mass M=2 kg, and length l=1 m, the value of ? is approximately : (take g = 10 m/s²)
