A record of travel along a straight path is as follows: 1. Start from rest with constant acceleration of 2.05 m/s2 for 14.0 s. 2. Maintain a constant velocity for the next 2.30 min. 3. Apply a constant negative acceleration of −9.41 m/s2 for 3.05 s. (a) What was the total displacement for the trip?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

2. Maintain a constant velocity for the next 2.30 min.
3. Apply a constant negative acceleration of −9.41 m/s2 for 3.05 s.
Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m
(b) What were the average speeds for legs 1, 2, and 3 of the trip, as well as for the complete trip?
| leg 1 | m/s |
| leg 2 | m/s |
| leg 3 | m/s |
| complete trip | m/s |
