Imaginary pressure blocks are used in this investigation to model sloping ocean surfaces resulting from density differences produced by variations in water temperature. While both temperature and salinity differences lead to currents, we are considering only temperature differences here. Also, keep in mind that our modeling of sloping surfaces using pressure blocks produces essentially the same results, although greatly exaggerated, compared to what happens to the sloping of ocean surfaces. We will examine “pressure blocks" as depicted in the following figures. Assume that the blocks employed in this investigation have the following characteristics: All blocks have the same weight (regardless of their volumes). The bases of all blocks are the same size. The red blocks have twice the volume of the blue blocks. 1. Because all blocks weigh the same, their masses must also be equal. Density is defined as mass per volume, so we know the densities of the red and blue blocks are different because their volumes are not the same. Since the volume of a blue block is half the volume of a red block, the density of a blue block is of a red block. the density а. half b. equal to c. twice

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
