# A miniature quadcopter is located at xi = 2.00 m and yi = 4.50 m at t = 0 and moves with an average velocity having components vav,x = 1.50 m/s and vav,y = −1.00 m/s. What are the (a) x-coordinate and (b) y-coordinate of the quadcopter’s position at t = 2.00 s?

(a)

To determine
The x -coordinate of the quadcopter’s position at t=2.00s .

Explanation

Given info: The x -coordinate of the quadcopterâ€™s position at t=0â€‰s is 2.00â€‰m . The x -coordinate of the quadcopterâ€™s average velocity is 1.50â€‰m/s .

Explanation:

The average velocity is defined as the ratio of the displacement to the time taken.

The formula for average velocity in the x direction is,

vav,x=Î”xÎ”t=xfâˆ’xiÎ”t

• xf is the final x coordinate
• xi is the initial x coordinate
• Î”t is the time taken

From the above equation, the final x coordinate is

xf=xi+vav,xÎ”t

Substitute 2

(b)

To determine
The y -coordinate of the quadcopter’s position at t=2.00s .
