Question
A protester carries his sign of protest, starting from the origin
of an xyz coordinate system, with the xy plane horizontal. He
moves 40 m in the negative direction of the x axis, then 20 m
along a perpendicular path to his left, and then 25 m up a water
tower. (a) In unit-vector notation, what is the displacement of
the sign from start to end? (b) The sign then falls to the foot of
the tower.What is the magnitude of the displacement of the sign
from start to this new end?

- A vector has both a direction and a "magnitude", or length. An example of a vector quantity is the wind, which has both a direction and a strength. What is the magnitude of the vector 32+ -93 +7k?arrow_forwardVector A has a magnitude of 5 at an angle of 36.9 counter clockwise from the x-axis. The components Ax and Ay are?arrow_forwardSuppose a person walks so that their displacement is represented by a vector that has a magnitude of 52m (vector A). The direction of that initial displacement is 31 degrees north of east. After that, the person then walks 15 m due west (vector B). Use trig to calculate the east and north components of the first displacement, vector A.arrow_forward
- In the next sets, you are given the magnitude and one component. There is an ambiguity in determining the vector, because you can only determine the absolute value of the other component and not its sign; therefore, there are two possibilities. In these tables, you must enter the absolute value of the component and provide two angles for the vector, the first one assuming the other component is positive and the other assuming the component is negative. You must also provide two angles for the antiparallel vector in the same order.

A player, starting at the y-axis, runs 8.50 yards, back (in the −x-direction), then 15.0 yards parallel to the y-axis (in the −y-direction).
