A 72-kg water skier is being accelerated by a ski boat on aflat (glassy) lake. The coefficient of kinetic frictionbetween the skiers skis and the water surface is = 0-25(Fig. 5-55). (a) What is the skiers acceleration if the ropepulling the skier behind the boat applies a horizontal tensionforce of magnitude FT = 240 N to the skier (0 = 0)?(b) What is the skiers horizontal acceleration if the ropepulling the skier exerts a force of FT = 240 N on the skierat an upward angle 6 = 12? (c) Explain why the skiersacceleration in part (b) is greater than that in part (a). FIGURE 5-55 99.
Chapter 1: A Modern View of the Universe 1.1: The Scale of the Universe – 1. What is our place in the Universe a. Our Cosmic Address i. Our Solar System – The place at which Earth is located along with other planets, moons, asteroids, and comets. Basically, everything the revolves around our Sun. 1. Our sun is just another star in space, like those we see in the night sky. ii. Milky Way Galaxy – our solar system belongs to the huge, diskshaped, collection of stars called the Milky Way galaxy. 1. A galaxy can be considered a great island of stars in space, all held
