The position vector of a point which moves in the x-y plane is given by: r = (- 0.2 t4 + 1.8 t3 + 1.1 t2) i + (- 0.4 t4 - 1.2 t) j where r is in meters and t is in seconds. Determine the angle between the velocity v and the acceleration a when t = 1.7 sec.
In multiple dimensions, specifying and objects position, displacement, velocity, and acceleration requires the use of vector notation. As we will see in the coming chapters, other quantities such as force and momentum are also vectors. A vector quantity has both a magnitude and a direction. For example, a person can walk a distance of 6 meters at an angle of 30o. By convention the angle is specified from the positive x-axis (East) unless otherwise specified. While this notation is useful...
