What is the velocity and starting position of the skater? </p><p> d. Was his speed constant over the entire interval? How do you know?</p><p> e. Write a mathematical representation (equation) to describe the line in terms of x and t.</p><p> f. Using the mathematical representation (equation) predict where the skater will be if he continues to skate at this rate for one minute. </p><p> g. How far from the origin will the skater in this problem be located after one hour? What assumptions do you have to make to solve this problem?</p><p> h. If this skater had begun at the origin, what constant speed would be required to reach the same final position at 10 seconds.</p><p>MHS PHYSICS GROUP 3 Constant Velocity WS1 Honors 4. The following motion diagram was drawn for a second trial:</p><p> a. Plot the position vs. time graph for the skater.</p><p> b. Was his speed constant? If so, what was it?</p><p> c. What is the mathematical representation (equation) of this skater? </p><p> d. How far from the starting point was he at t = 5s? How do you know?</p><p> e. Using the mathematical representation (equation) above how much time would it take this skater to skate one kilometer (1000m).</p><p> f. In question 3 the skater was further along at 2s than in question 4. Does this mean that he was going faster? Explain your answer.</p><p> g. If this skater had begun at the origin, what constant speed would be required to reach the same final position at 4 seconds?</p><p>MHS PHYSICS GROUP 4 Constant Velocity WS1 Honors </p>
