Problem 1 A block of wood is attached to the bottom of a lake by means of a rope and it is completely immersed in the water. The wood has a density of 0.25 x 103 kg/m³ (while water has a density of 1.0 x 10°kg/m³). a) Compute the absolute and gauge pressure 5.0 meters below the surface of the lake (use the value po 1.01 × 105 Pa for the atmospheric pressure). b) If the the volume of the block is V = 0.0136 m³, what is the tension in the string? c) If we cut the rope, the block will start accelerating towards the surface. Calculate the acceleration.
