Problem 1. The expression y =0.2t 3 + 1.8t 2 3t + 14 ft describes the position of a
particle moving along the y axis over the time interval ( 0 t 4 s ) . On that time
interval, deter

Motion
As we recall from earlier, in radial and transverse
components, we define motion in terms the distance
from the origin of coordinates, r, and
Lecture 5
As a pedagogical question, is there a difference between the meanings of the terms constant
velocity and constant speed?
Dependent Motion
Consider two particles where the motion of one parti

Consider a particle moving along a
curved path with velocity v as shown.
The parameter s denotes distance along
the path.
