The letters A to E correspond to various segments of the motion in which the graph has constant slope x (m) 0 1 (s) 2 4 68 10 12 14 18 Q Tap image to zoom Part A

Solution

(a)

the slope of the graph indicates the velcoity of the object.

At point B and D, the slope of the graph is zero.

therefore, the object is in rest at points B and D.

(B)

The slope of thegraph is positive at point A, this sign indicates the direction of the object. Since the slope is positive, the object moves to the right at point A.

(C)

The speed of the object during segment C less than its speed during segment E.

slope of the graph is less than at point C compared to the slope of the graph at point E.
