Textbook Question
Chapter 2, Problem 31P
ǀ BIO If a pilot accelerates at more than 4g, he begins to “gray out,” but not completely lose consciousness. (a) What is the shortest time that a jet pilot starting from rest can take to reach Mach 4 (four times the speed of sound) without graying out? (b) How far would the plane travel during this period of acceleration? (Use 331 m/s for the speed of sound.)

Suppose a car merges into freeway traffic on a 200 -m-long ramp. If its initial velocity is 10 m/s and it accelerates at 2 m/s2, how long does it take to travel the 200 m up the ramp? (Such information might be useful to a traffic engineer.)
v0=__m/s
A train is traveling down a straight track at 35 m/s when the engineer applies the brakes, resulting in an acceleration of −1.0 m/s2 as long as the train is in motion. How far does the train move during a 70-s time interval starting at the instant the brakes are applied?? m
Car A is parked along the northbound lane of a highway, and car B is traveling in the southbound lane at a constant speed of 60 mi/h. At t=0, A starts and accelerates at a constant rate a A , while at t= 5 s, B begins to slow down with a constant deceleration of magnitude a A 6. Knowing that when the cars pass each other x = 294 ft and VA = VB , determine (a) the acceleration aA,(b) when the vehicles pass each other, (c) the distance d between the vehicles at t=0.

Behind the freight train on the same track is a passenger train traveling in the same direction at 40.0 m/s. When the front of the passenger train is 58.5 m from the back of the freight train, the engineer on the passenger train recognizes the danger and hits the brakes of his train, causing the train to move with acceleration 3.00 m/s2. Because of the engineers action, the trains do not collide.arrow_forwardA California Condor is approaching its nest with a large chunk of carrion in its beak.
