A swimming pool is 30 ft wide and 60 ft long and its bottom is an inclined plane, the shallow end having a depth of 4 ft and the deep end, 8 ft . Assume the pool is full of water. (Round your answers to the nearest whole number. Assume that the weight density of this water is \( 62.5 \mathrm{lb} / \mathrm{ft}^{3} \).) (a) Estimate the hydrostatic force (in Ib) on the shallow end. \( \times \mathrm{lb} \) (b) Estimate the hydrostatic force (in lb) on the deep end. \( \times \mathrm{lb} \) (c) Estimate the hydrostatic force (in Ib) on one of the sides. \( \times \mathrm{lb} \) (d) Estimate the hydrostatic force (in Ib) on the bottom of the pool. \( \times \mathrm{lb} \) Need Help?
