Question
7. ( 15 points) An empty box in the shape of a cube is completely submerged under water. The exterior side of the box has length L = 1.00 m as shown in Figure 1. The mass of the box is M = 60.0 kg. (a)(5 points) Does the box sink or rise ? Show all work to prove your answer! (b)(5 points) What is the magnitude a of the acceleration of the box? (c) (5 points) Suppose a lead block of mass m = 75.0 kg is placed inside the empty box. See Figure 2. What is the magnitude and direction (up or down) of the acceleration of the box?
