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.

a cat is setting at the end of a long hallway. a mouse is running away from the cat , at a constant velocity of 1.58 m/s. whe the mouse is 3.43 meters away from the cat, the cat gets up and accelerates from rest at a constant rate of 1.99 m/s squared to catch the mouse.How much time does it take the cat to catch the mouse?  How far does the cat run before catching the mouse?

A truck, stolen by Dora the Explorer is initially stopped 10.0 m from the base of a building. Peppa pig is 22.0 m above the ground on the balcony of her office building. The truck begins to accelerate towards the building. One second after the truck moves, Peppa pig jumps off the balcony. Peppa pig, in an attempt to stop Dora the Explorer, times her fall perfectly and lands on the truck, which is 3.0 meters above the ground. What was the acceleration of the truck and its final velocity (assume constant acceleration)?

Joe takes his dog to the local dog park every morning, too. He walks with his dog blocks south, 5 blocks west, and 5 blocks north in order to get to the park. What is his total displacement?

Your roommate drops a tennis ball from a third-story balcony. It hits the sidewalk and bounces as high as the second story. Draw a motion diagram, using the particle model, showing the ball’s velocity vectors from the time it is released until it reaches the maximum height on its bounce.

A rock is thrown from a cliff and lands 20.2 m from the base of the cliff, and it was thrown horizontally with a speed of 12.7 m/s. a.) How tall is the cliff?

Starting from the front door of your ranch house, you walk 60.0 m due east to your windmill, and then you turn around and slowly walk 35.0 m west to a bench where you sit and watch the sunrise. It takes you 30.0 s to walk from your house to the windmill and then 46.0 s to walk from the windmill to the bench. For the entire trip from your front door to the bench, what is your average speed?

Chapter 02, Problem 034 GO Z Your answer is partially correct. Try again. In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at x, = 0 and the green car is at x, = 223 m. If the red car has a constant velocity of 23.0 km/h, the cars pass each other at x = 44.8 m. On the other hand, if the red car has a constant velocity of 46.0 km/h, they pass each other at x = 76.2 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs. Green car Red car (a) Number-19.993 Unit m/s^2 (b) Number |-1.544 Unit m/s^2 Click if you would like to Show Work for this question: Open Show Work

Jim is driving his car at 32m/s (72mi/h) along a highway where the speed limit is 25m/s (55mi/h). A highway patrol car observes him pass and quickly reaches a speed of 36m/s. At that point, Jim is 300m ahead of the patrol car. How far does the patrol car travel before catching Jim?

Wyle E. Coyote hears a constant “Beep! Beep!” from around the corner of a cliff. Thinking it might be the Road Runner, he scampers up to speed and runs towards the sound to the East. On coming around the corner, he sees that it is not the Road Runner, but a truck coming towards him towards the West. The speed of the truck is 25 m/s. The speed of the Coyote is 100 m/s. The Coyote hears a frequency of 5500 Hz. The temperature of the air is 300 K. The mass of the truck is 1500 kg. The mass of the Coyote is 90 kg. Assume the air is an ideal gas with γ = 1.40 and the air molecules have a mass of 4.8*10-26 kg. The Boltzmann constant is k = 1.38*10-23 J/K. a. What is the speed of sound in this air? b. What is the original frequency of the horn on the truck? c. Assuming a perfectly inelastic collision, what is the final speed and direction of the truck, Coyote conglomerate (ignore any friction with the road)?
