Example: A car traveled half of the way at speed v1, the rest of the way it traveled half the time at speed v2, and the last section at speed v3. Find the average speed of the car along the entire way. Solution: By definition, average speed is the ratio of total path to total ...
16.5.2The Right-Hand Rule There are two orientations for each axis,\(2^3=8\)orientations overall. What matters is the relative orientation of one axis with respect to the other two; for example, once thex- andy-axes have been chosen to lie in the plane of the paper, thez-axis can...
᭣ In discussing the equations of kinematics, it will be convenient to assume that the ob- ject is located at the origin x0 ϭ 0 m when t0 ϭ 0 s. With this assumption, the displace- ment ⌬x ϭ x Ϫ x0 becomes ⌬x ϭ x. Furthermore, it is customary to dispense ...
