Problem 2.72

A record of travel along a straight path is as follows: 1. Start from rest with a constant acceleration of 2.77 m/s2 for 15.0 s. 2. Maintain a constant velocity for the next 2.05 min. 3. Apply a constant negative acceleration of 9.47 m/s2 for 4.39 s. (a) What was the total displacement for the trip? (b) What were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip?

Step 1 of 3

PHYS 1010 Notes Week 12 April 4­8 General theory of relativity ­ Covers accelerating and non­accelerating reference frames ­ You can always tell if you are accelerating by dropping an object and watching it move, but we can't distinguish between an accelerating reference frame and gravity ­ Airplanes travel in curved paths because they take the shortest route possible. They fly closer to the North or South Pole and then back down because the earth is smaller further from the equator ­ Light can travel in a curved path because space itself is curved; on a curved surface, the fastest path is curved ­ So, gravity exists because mass curves space ­ Mass creates an indentation in space­time, which explains the attrac
