Question

Graph of displacement (X) vs time (t) is given below for a particle moving in one dimensional motion.The velocity time graph for this case is__.give complete explanation.​

Answer 1

Answer:

option 1

Explanation:

just find velocity after each 5 second and plot the graph

Answer 2

Explanation:

option one is correct because if we find the Slope of a graph which denotes the velocity

we found that at starting from position 0 to 15 seconds the slope must be positive it means the velocity is positive

whereas after 15 seconds the time interval from 15 to 20 the slope is negative it means the velocity is negative

if you notice from time interval 5 to 10 second slope is zero the velocity is also zero

if you read all these conditions then we will find that the graph first matches these points therefore option A is the correct answer
