Question

draw a velocity -time graph for uniform motion when initially body is not at rest​

Answer 1

Explanation:

When the body is at rest, its speed is zero, and the graph lies on the x-axis.

When the body is in uniform motion, the speed is constant, and the graph is a horizontal line, parallel to the x-axis and some distance above it.

It's impossible to tell, based on the given information, how these two parts of the graph are connected. There must be some sloping (accelerated) portion of the graph

that joins the two sections, but it cannot be accounted for in either the statement that the body is at rest or that it is in uniform motion, since acceleration ... that

is, any change of speed or direction ... is not 'uniform' motion'.
