Question

velocity time graph of a body is shown below

Answer the following
1. which part of the graph shows the decelerated motion?
2. which part of the graph show the uniform motion
3.calculate the distance of the journey .
​

Answer 1

Answer:

Explanation:(a)Since velocity is not changing, acceleration is equal to zero.

(b) Reading the graph, velocity=20ms

−1

(c) s = area of the figure enclosed under v-t graph. Distance covered in 15s, s=ut=20×15=300m
