37. 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 θ before momentarily coming to rest. If the rod has mass M = 2 kg, and length l = 1 m, the value of θ is approximately: (take g = 10 m/s²) (a) 63° (b) 55° (c) 69° (d) 49°

solution 63
