A graph of position versus time for a certain particle moving along the x-axis is shown in Figure P2.6. Find the average velocity in the time intervals from (a) 0 to 2.00 s, (b) 0 to 4.00 s, (c) 2.00 s to 4.00 s, (d) 4.00 s to 7.00 s, and (e) 0 to 8.00 s. Figure P2.6 (Problems 6 and 17)

(a)

To determine
The average velocity of the particle in 0 to 2.00s .

Explanation

Given info: The initial position of the particle in the interval is 0 , the final position of the particle in the interval is 10.0m , the initial time of the interval is 0 , and the final time of the interval is 2.00s .

Explanation:

The formula used to calculate the average velocity is,

v¯=xfxitfti

Here,

v¯ is the average velocity.

xf is the final position.

xi is the initial position.

tf is the initial time.

ti is the final time.

Substitute 10.0m for xf , 0 for xi , 2

(b)

To determine
The average velocity of the particle in 0 to 4.00s .

(c)

To determine
The average velocity of the particle in 2.00s to 4.00s .

(d)

To determine
The average velocity of the particle in 4.00s to 7.00s .

(e)

To determine
The average velocity of the particle in 0 to 8.00s .
