A runner with a good awareness of her pace runs along a path of unknown length at a speed of 0.1250.125 mi/min and then walks back to her starting point at a speed of 0.04500.0450 mi/min. She neglects to note her time for each part of her path but does measure the total round-trip time to be 50.050.0 min. How far did she run? (Do not include walking distance.)
A tortoise and a hare are in a road race to defend the honor of their breed. The tortoise crawls the entire 1000 meters at a speed of 0.2 m/s. The rabbit runs the first 200 meters at 2 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800 meters with an average speed of 3 m/s. Who wins the race and by how much time?
To burn the fats she accumulated during the lockdown, Katie walks south at a speed of 2.00 m/s for 60.0 minutes. She then turns around and walks north a distance 3000 m in 25.0 minutes. What is her total distance covered?

- 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?arrow_forwardWe travel from Winnipeg to Regina and back. The total distance is 1100km. The return to Winnipeg is made in a snowstorm at an average speed of 20km/h slower than the outward journey. If the whole trip took 13 hours, what is the average speed in each direction?arrow_forwardA tortoise can run with a speed of 0.11 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 1.0 minutes. The tortoise wins by a shell (40 cm). How long does the race take? What is the length of the race?arrow_forward
- A hare and a tortoise are having a race along a 2.0km track. The tortoise sets off at a constant speed of 1.6 m/s. The hare is confident that they can win, so first do 1000 meters at 5 m/s turns around and sees the hare and so stops and falls asleep for 10 mins. The hare wakes up and then sees the tortoise too close so speeds up again at 5m/s for another 500 meters after which the Hare again decides to sleep for 5 mins being so are in front. The Hare wakes up and sees the Tortoise! He dashes for the finish another 500 meters away at 8 m/s. To no avail as the story goes. By how much did the Tortoise win?arrow_forwardMaria throws two stones from the top edge of a building with a speed of 1.2 × 10' m/s. The height of the building is 9.6 x 10- meters. She throws one straight down and the other straight up. The first one hits the street in a time t1. How much later is it before the second stone hits? answer in seconds.arrow_forwardA car starts from rest and accelerates at a constant 10 m/s2 during aquarter-mile (402 m) race. How fast is the car going at the finish line? I know the answer to this problem is 90 m/s, but I don't know how the book i found it in came to this answer. How am I supposed to solve this problem without knowing either final velocity or time?arrow_forward
- Maria throws two stones from the top edge of a building with a speed of 2.9 x 10' m/s. The height of the building is 7 x 102 meters. She throws one straight down and the other straight up. The first one hits the street in a time tj. How much later is it before the second stone hits? answer in seconds.arrow_forwardA straight running track is 2400 m long. A runner starts from the start line of the track, runs to the end line, and immediately turns back to run back to the starting point. After running for a total of 30 minutes, the runner was able to complete one whole round trip and is now halfway through the track on his second trip towards the end line. What was the runner's average speed in m/s? Answer:arrow_forwardThe velocity of a rat traveling on a straight line is v(s)=1/(s+1), where the velocity is in meters per second and s is in meters. the rat travels 10 meters from s=0 to s=10m. Assume s=0 when t=0. 1. The total time it took for the rat to reach s=10m is ____s. 2. The expression for the position as a function of time is s(t)=_____. 3. The absolute maximum (maximum of absolute values) acceleration of the rat during the 10-meter trip is ____ m/s^2. Please help solve these questions, the solutions are given below I'm just not sure how to solve it. (Use paper sheet ,Not Typewritten) The solutions are: 1) 110 2)(sqrt(t+0.25))-0.5 3)1.00arrow_forward
- My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she runs 4.12 meters from the middle of our living room to our kitchen, where she is satiated with her grub. If it takes her 4.45 s to get to the kitchen, what was her speed in m/s to the nearest hundredth?arrow_forwardTired, 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?arrow_forwardTo deter speeding through a residential area, the Police set up a speed trap on Illusion Drive. Between the hours of 3:00 pm and 6:00 pm, they time vehicles over a 50 meter distance. If the speed limit is 30 mph, what is the fastest a driver can cover this distance and NOT receive a ticket? 1.7 seconds 5.0 seconds none of these 8.0 seconds 3.7 secondsarrow_forward
