- How does something that operates in milliseconds compare to something that operates in nanoseconds? What is the difference in terms of the order of magnitude?Usain Bolt from Jamaica holds the world record for the 100 meter race running it in 9.58 seconds. How fast is this in miles per hour? Assume that 100 is an exact number. 1 mile = 1.609 km.2.
- Tom Cogwagee Longboat, of the Six Nations of the Grand River, is one of Ontario's best known distance runners. In 1907, he set a new Boston Marathon record, beating all of the previous decade's champions by almost 5 minutes! If he ran the 39.2 km course in 2 hours, 24 minutes and 24 seconds, what was his speed? HINT: we'll need our units to be metres per second - what do you need to convert in the question? 0.221 m/s O 0.272 m/s O 4.52 m/s O 17.5 m/sDuring 55 successive 1.001.00 min intervals, a runner moves at the following constant speeds: 0.4000.400 km/min, 0.2000.200 km/min, 0.1100.110 km/min, 0.1100.110 km/min, and 0.3600.360 km/min. a.) Find the total distance traveled. b.) Find the average speed.5. When 12 times a number is added to the square of that number, the result is ‒32. Determine the two numbers that fit this condition. Answer step-by-steps. 6. A cannonball is fired from ground level on an arc described by h = ‒t2 + 8t, where h = the height in metres and t is the time in seconds. How many seconds after firing will it land? Answer step-by-steps.
- A please4. A computer animator is trying to make an animation of a rabbit rushing back and forth along a sidewalk. He decides to model the rabbit's velocity over time as shown in the following graph, where time is measured in seconds and velocity is measured in meters per second. velocity 3 2 1 777749 -24 -4 -5 3 4 8 9 time 10 (Here, positive velocities indicate that the rabbit is heading east; negative velocities indicate that the rabbit is heading west.) (a) Suppose the rabbit starts at a position we'll call 0. Sketch a rough graph of the rabbit's position as a function of time on the interval [0, 10]. We do not expect your graph to be perfect, but it should accurately show whether the graph is increasing or decreasing and whether it is concave up or concave down. (b) At time 0, there was a squirrel sitting 2 meters east of the rabbit. Suppose that the squirrel's velocity on [0, 10] is given by the same graph shown above. On your graph from (a), also sketch the squirrel's position as a…USE THE CORRECT NUMBER OF SIGNIFICANT FIGURES IN THE ANSWER!
