Question

Part A

Consulting the graph shown in the figure, find the object's average velocity over the time interval from 0 to 1 second.

Answer to the nearest integer.

Part B

Find the average velocity over the time interval from 1 to 3 seconds.

Express your answer in meters per second to the nearest integer.

Part C

find vave[0,3].

Give your answer to three significant figures.

Part D

Find the average velocity over the time interval from 3 to 6 seconds.

Express your answer to three significant figures.

Part E

Finally, find the average velocity over the whole time interval shown in the graph.

Express your answer to three significant figures.

m/s

Explanation / Answer

Part A:

in bet ween 0 to 1 second given object is stationary

then average velocity will be zero

PArt B :

in this case the change in the position is about = 40 m

and now the time interval = 2 s

then the average velocity = 40 / 2

= 20 m/s

Part C :

in this case the change in the position is about = 40 m

and now the time interval = 3 s

then the average velocity = 40 / 3

= 13.3333 m/s

Part D :

in this case the change in the position is about = - 40 m

and now the time interval = 3 s

then the average velocity = - 40 / 3

= - 13.3333 m/s

Part E :

in the this case object returned towards the origin

so there is no change in the position

obviously the average velocity must be zero
