Question

13)What can you say about the motion of a body if its velocity-time graph is a straight line inclined with the time axis?

The body moves with uniform velocity.

14)Which of the following conclusions can be drawn if a velocity-time graph is parallel to the time axis?

A)The body is moving with uniform velocity
B)its acceleration is zero
C)its speed can be found by finding the area of the graph.
D)both A and B

I don't know B?

Answer 1

13). No, since the graph is inclined, velocity is not constant. There is a steady acceleration.

14.) The answer is D)
