Textbook Question
Chapter 2, Problem 32P
A small propeller airplane can comfortably achieve a high enough speed to take off on a runway that is 1/4 mile long. A large, fully loaded passenger jet has about the same acceleration from rest, but it needs to achieve twice the speed to take off. What is the minimum runway length that will serve? Hint: You can solve this problem using ratios without having any additional information.

Such massive ships require a distance of 5.1 km (about 3.2 mi) and a time of 21 min to come to a stop from a top speed of 29 km/h. What is the magnitude of such a ship's average acceleration in m/s2 in coming to a stop? _______m/s2 What is the magnitude of the ship's average velocity in m/s? m/s Comment on the potential of a tanker running aground.

- One of the most difficult things to learn in physics is that our everyday language is not always precise enough. For instance, we might say a car is “slowing down”, but that only gives us information abouts velocity, not its acceleration. What can we say about the velocity of a car which has negative acceleration in the x-direction? a. It is slowing down. b. The x-component of its velocity is decreasing. c. The x-component of its velocity is negative. d. It is speeding up. e. The x-component of its velocity is positive. f. The x-component of its velocity is increasing.arrow_forwardIf it takes 50 m to stop a car intially moving at 25 m/s, what distance is required to stop a car moving at 50 m/s in the same conditions? a. 50 m b. 100 m c. 200 m d. 400 marrow_forwardA UCI student is running at her top speed of 5.1 m/s to catch a Shuttle bus, which is stopped at the bus stop.
