Lym. 600 L Problem 56. Two rods, each of length 1-0.5m and mass m, 1 kg, are joined together by hinges as shown. The bottom end of the left rod is connected to the ground, while the bottom end of the right one is connected to a block of mass m₂=2 kg. The block is then released to a position where the rods form a 60° angle with the horizontal plane. Friction is negligible. a) Find the velocity of point A as it hits the ground. b) Find the acceleration of mass my at that moment.
