Question

A dragonfly flies from point A to point B along the path shown in the figure in 2.10s

A dragonfly flies from point A to point B along the path shown in the figure in 2.10s Find the x and y components of its position vector at point A. Express your answers in meters, separated by a comma. What is the magnitude of its position vector at A? What is the direction of its position vector at A? Find the x and y components of the dragonfly's average velocity between A and B. What is the magnitude of its average velocity between these two points? press your answers in meter per second, separated by a comma.

Explanation / Answer

1. (2m,1m)

2.root(2^2+1^2) = root(5) = 2.236 m

3. direction at A is 26.56 degrees from x axis towards y axis counter clockwise.

4. av velocity in x direction = 10-2 / 2.1

= 3.81 m/s

av velocity in y direction = 6-1 / 2.1

= 2.38 m/s

(3.81m/s , 2.38m/s )

5. magnitude of av velocity = root(3.81^2 + 2.38^2) = 4.49 m/s

6. direction of av velocity is 32 degrees form x axis counterclockwise
