Displacement and Velocity Vectors Questionnaire

Description

1. After an arduous journey, a pirate comes to the last two steps of a treasure map. It indicates to travel 14 m southward, then turn 17° to one’s left and travel another 22 m to the buried treasure. The mathematically astute pirate decides to just find the magnitude and direction of the total displacement vector and go along that path.

Determine the magnitude of the direction of the displacement vector, as an angle south of East. In other words, if you calculate the angle to be 30-degrees below East, then you would record “30” in the space provided.

?=______?southofeast

2. A car drives 207 meters north in 10 seconds and then 281 meters south in 7 seconds. Taking north to be the positive x-direction and south to be the negative x-direction, find the average speed of the car in meters per second during its trip.

v=______m/s

3. An object moves from point A to point B along a given path. What must be known in order to calculate displacement? Choose all that apply.

Group of answer choices

The positions of points A and B

The length of the path

The time required to move from point A to point B

The instantaneous velocity at the starting and ending points
