Question

according to the given velocity - time graph of object ​

Answer 1

Answer:

Is moving uniformly with some initial velocity.

Explanation:

Is moving uniformly with some initial velocity.

Answer 2

According to the given velocity-time grapgh the object (3) is moving uniformly with some initial velocity.

Explanation:

Initial velocity: Initial velocity is the velocity observed at t=0. It is denoted by 'u'.

According to the graph, at t=0, v≠ 0. This tells us that there is some initial velocity present. In addition, the velocity is increasing uniformly at any given time "t".

Explanations of incorrect answers-

(1) is moving with uniform velocity- in addition to uniformly it has some initial velocity. More appropriate answer is (c)

(2) has some initial velocity-in addition to some initial velocity it is moving uniformly. More appropriate answer is (c)

(4) is at rest- a body at rest will have no velocity i.e. v=0

Hence, the object (3) is moving uniformly with some initial velocity.
