- An object moves along the x axis according to the equation x = 3.00t2 2.00t + 3.00, where x is in meters and t is in seconds. Determine (a) the average speed between t = 2.00 s and t = 3.00 s, (b) the instantaneous speed at t = 2.00 s and at t = 3.00 s, (c) the average acceleration between t = 2.00 s and t = 3.00 s, and (d) the instantaneous acceleration at t = 2.00 s and t = 3.00 s. (e) At what time is the object at rest?An object moves along the positive x-axis with a speed of V, =4 m/s for 2 seconds, then moves along the negative x-axis with a speed of V2 =7 m/s for 2 seconds and then moves along the positive x-axis with a speed of V3 =25 m/s for 2 seconds What is the average speed of the object (m/s)?A tortoise and a hare are competing in a 1200-meter race. The arrogant hare decides to let the tortoise have a 820-meter head start. When the start gun is fired the hare begins running at a constant speed of 8 meters per second and the tortoise begins crawling at a constant speed of 4.5 meters per second. Which of the following formulas expresses the distance between the tortoise and the hare in meters, d, in terms of the number of seconds, t, since the start gun was fired? Od = 820 - 8t Od = 820 + 3.5t Od = 820 - 3.5t Od = 1200 3.5t Od = 1200 - (8t + 4.5t)
- You start out by driving 82 miles north in 4 hours and 36 minutes, and then you stop and park for a while. Finally you drive another 60 miles south in 3 hours and 11 minutes.

(Round your answer to one decimal place.) miTwo cars leave an intersection, one 17 minutes after the other. The first car, A, travels north at the speed of 50 km/h and the second car, B, travels west at a speed of 70 km/h. How fast are the cars separating from each other 55 minutes after the first car leaves the intersection? the answer is 85, but I am struggling on how to find that answerYou are driving home from school steadily at 97 km/hkm/h for 160 kmkm . It then begins to rain and you slow to 61 km/hkm/h instantly. You arrive home after driving 4.5 hours. How far is your hometown from school? answer using two significant figures. What was your average speed? answer using two significant figures.
- A runner and a cyclist compete in a race over a straight course 20 km long. The runner runs at a steady speed of 10 m/s toward the finish line. The cyclist zips at a speed of 23 m/s toward the finish line for 12 km but upon seeing that he is already far ahead of the runner, he decides to stop and wait for the runner to catch up to him. The runner eventually reaches the cyclist and continues moving toward the finish line. The cyclist waits for a while after the runner passes and then cycles toward the finish line again at 23m/s. Both the cyclist and the runner cross the finish line in the exact same instant. Assume both of them, when moving, move steadily at their respective speeds. (a) How far is the runner from the finish line when the cyclist resumes the race? (b) For how long in time was the cyclist stationery?A gazelle and a mouse participate in a race over a 2.00 km long course. The gazelle travels at a speed of 15.0 m/s and the mouse can do 2.50 m/s. The gazelle runs for 1.600 km and then stops to tease the slow-moving mouse, which eventually passes by. The gazelle waits for a while after the mouse passes and then runs toward the finish line. Both animals cross the finish line at the exact same instant. Assume both animals, when moving, move steadily at their respective speeds. (a) How far (in m) is the mouse from the finish line when the gazelle resumes the race? (b) For how long in time (in s) was the gazelle stationary?Tired, you walk from your house to a local coffee shop to get an espresso. You average a speed of 2.4 m/s on your way there. After your espresso, you decide to run directly back to your starting point with an average speed of 5.6 m/s. Assume you spend 4 minutes at the coffee shop. If your average speed for this entire trip is 1.9 m/s, what is the distance between your house and the coffee shop?
