When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 50 s to walk from your gate to baggage claim. When it is working and you stand on the moving sidewalk the entire way. without walking. it takes 75 s to travel the same distance. How long will it take you to travel from the gate to baggage claim if you walk while riding on the moving sidewalk?

An airport terminal has a moving sidewalk to speed passengers through a long corridor. Larry does not use the moving sidewalk; he takes 150 s to walk through the corridor. Curly, who simply stands on the moving sidewalk, covers the same distance in 70 s. Moe boards the sidewalk and walks along it. How long does Moe take to move through the corridor? Assume that Larry and Moe walk at the same speed.

- Hello, I had a physics question. "Just as the traffic light changes to green, a Mustang drives through the intersection at a constant velocity of 14.2 m/s [N]. A Camaro that was stopped at the light accelerates from rest at 2.9 m/s^2 [N]. How much time passes before the two cars meet again? How far have they travelled? I figured out how to do the question but I'm really confused on the units of the distance. I used the d = v/t formula and the vit + 1/2at^2 formula but the units I ended up getting were m^2/s^3 for distance when it should just be m.arrow_forwardYou are riding the Power Tower, an amusement park ride in which you sit in a chair raised 387 m above the ground. When the ride begins, you are carried downward at a constant speed of 36.0 m/s. a) You drop a ball from rest at the moment you begin moving downward. At what height above the ground will the ball catch up with you? b) How fast will the ball be moving when it hits the ground?arrow_forwardYou encounter a moving walkway that is 81 m long and has a speed of 2.1 m/s relative to the ground. How long would it take you to cover the 81 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.6 m/s relative to the walkway? Express your answer using one significant figure.arrow_forward
- Moving sidewalks are installed every other 50 meters along the entire stretch of an airport walkway. These sidewalks move at a constant speed of 1 m/s. A lady passenger takes one of the sidewalks to go from one point to the next. If the passenger decides to go back using the same sidewalk at 1 m/s, how long will it take to reach her point of origin?arrow_forwardYou're helping a friend move in to their apartment on the second floor, and decide it makes more sense to throw a box straight up from the ground to the open window in the apartment, 5.00 m above the ground. Your friend leans out the window and catches the box while it's moving upward at 2.40 m/s. What is the speed of the box as it left your hand?arrow_forwardI'm not sure how to solve this! I tried and got 1.3 / 2.4 seconds. Am i right? Could you explain how to do it if i'm not? Cheers ! In a classic Seinfeld episode, Jerry tosses a loaf of bread (a marble rye) straight upward to his friend George who is leaning out of a third-story window. If the loaf of bread leaves Jerry's hand at a height of 1 m with an initial velocity of 18 m/sec, write an equation for the vertical position of the bread s (in meters) t seconds after release. How long will it take the bread to reach George if he catches the bread on the way up at a height of 16 m? Round to the nearest tenth of a second.arrow_forward
- Moving sidewalks are installed every other 50 meters along the entire stretch of an airport walkway. These sidewalks move at a constant speed of 1 m/s. A lady passenger takes one of the sidewalks to go from one point to the next. If the passenger simply stands on the sidewalk, how long will it take her to reach the next point? If the passenger walks at 1.25 m/s, how long will it take her to reach the next point?arrow_forwardNASA is launching a rocket into space from Earth. This particular rocket burns its fuel for 5 minutes and then turns off its engines. At this point, the rocket keeps floating along through space at a speed of 10 km/s. What is the rocket’s average acceleration during these first 5 minutes? Part 2: How far did the rocket travel during the first 5 minutes? Part 3: The Moon is approximately 3.8.105 km from Earth. At its final speed, how long will it take the rocket to reach the Moon? Part 4: The star nearest to us, called Alpha Centauri, is 4.1.1013 km away. Could this rocket get a man to Alpha Centauri before he dies of old age? (This is a real obstacle to NASA’s plans of exploring other solar systems than our own!) Part 5: The rocket is half way to the Moon when its pilot suddenly notices he forgot his camera! He radios a second rocket crew on Earth and tells them to bring his camera and meet him on the Moon when he lands. Unfortunately, the second rocket can only…arrow_forwardA moving walkway at an airport has a speed v1 1 and a length L. A woman stands on the walkway as it moves from one end to the other, while a man in a hurry to reach his flight walks on the walkway with a speed of v2 relative to the moving walkway. (a) How long does it take the woman to travel the distance L? (b) How long does it take the man to travel this distance?arrow_forward
- Christopher watches a stick float downstream in a river and notices that it moves 15 m [El in a time of 2.5 x 10' s. His friend, John, is starting on the south side of the river and is going to swim across. In still water, John knows that he can swim with a speed of 1.2 m/s, relative to the water. a) What is John's velocity relative to the shore? b) If the river is 1.5 km wide, how long will it take John to cross the river? c) How far downstream will be land?arrow_forwardAnswer parts a, and b of the following question. 7. a) Arthur and Betty start walking toward each other when they are 100 m apart. Arthur has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. How long does it take for them to meet? b) The captain orders his starship to accelerate from rest at a rate of "1 g" (1 g = 9.8 m/s2). How many days does it take the starship to reach 10% the speed of light? (Light travels at 3.0 × 108 m/s.)arrow_forwardOK, this is the last time for one of these crazy adventures. THIS time, though, there is a window in the floor, and you can see that you re in a rocket which has just taken off from the surface an alien planet. By taking careful measurements out that window you determine that the rocket is accelerating upward at 8.14 m/s^2. When you drop a ball from a height of 2.15 m, it hits the floor 0.200 s later. What is the value of g for the alien world below you?arrow_forward
