# An ant crawls on the floor along the curved path shown in Figure P3.4. The ant’s positions and velocities are indicated for times ti = 0 and tf = 5.00 s. Determine the x- and y-components of the ant’s (a) displacement, (b) average velocity, and (c) average acceleration between the two times.Figure P3.4

(a)

To determine
The x and y components of the ant’s displacement.

Explanation

Given info: The final x coordinate of the antâ€™s position is 0.400â€‰m , the initial x coordinate of the antâ€™s position is 0.100â€‰m , the final y coordinate of the antâ€™s position is 0.350â€‰m and the initial y coordinate of the antâ€™s position is 0.150â€‰m .

Explanation:

The x component of the antâ€™s displacement is,

Î”x=xfâˆ’xi

• xf is the final x coordinate
• xi is the initial x coordinate

Substitute 0.100â€‰m for xi and 0.400â€‰m for xf .

Î”x=0.400â€‰mâˆ’0.100â€‰m=0

(b)

To determine
The x and y components of the ant’s average velocity.

(c)

To determine
The x and y components of the ant’s average acceleration.
