Step 1

Note: Since we only answer up to 3 sub-parts, we’ll answer the first 3.

Please resubmit the question and specify the other subparts (up to 3) you’d like answered.

For a body moving along a coordinate line it is required to determine the following from the graph given below:

Part a) The time when the body reverse direction.

Part b) The time when the body is moving with a constant speed.

Part c) Speed-time graph for the body on the time interval 0 to 10 seconds.

Step 2

Part a)

When a body moving along a coordinate axis changes its direction the sign of the velocity changes.

Observe form the velocity-time graph given below that the velocity of the body changes from positive to negative at the point x = 2 and from negative to positive at the point x = 4. help_outlineImage TranscriptioncloseAv (m/sec) 5- V= {(t) (sec) 10 6 fullscreen
Step 3

When the body is moving with a constant speed the velocity-time graph of the body is a straight line parallel to the x-axis.

Observe that t... help_outlineImage TranscriptioncloseAv (m/sec) 5 V= (t) (sec) 10 6 fullscreen
