A skater glides along a circular path of radius 5.00 m. If he coasts around one half of the circle, find (a) the magnitude of the displacement vector and (b) how far the person skated. (c) What is the magnitude of the displacement if he skates all the way around the circle?
Answer to relevant QuestionsA force F1 of magnitude 6.00 units acts at the origin in a direction 30.0° above the positive x axis. A second force F2 of magnitude 5.00 units acts at the origin in the direction of the positive y axis. Find graphically ...A roller coaster car moves 200 ft horizontally, and then rises 135 ft at an angle of 30.0° above the horizontal. It then travels 135 ft at an angle of 40.0° downward. What is its displacement from its starting point? Use ...In 1992, Akira Matsushima, from Japan, rode a unicycle across the United States, covering about 4 800 km in six weeks. Suppose that, during that trip, he had to find his way through a city with plenty of one-way streets. In ...Consider the three displacement vectors A = (3ˆi ─ 3ˆj) m, B = (ˆi ─ 4ˆj) m, and C = (─2ˆi + 5ˆj) m. Use the component method to determine (a) the magnitude and direction of the vector D = A + B + C, ...The vector A has x, y, and z components of 8.00, 12.0, and ─ 4.00 units, respectively. (a) Write a vector expression for A in unit–vector notation. (b) Obtain a unit–vector expression for a vector B one fourth ...
