Question

A-4.
Shown in the figure are the position time graph for two children going home
from the school. Which of the following statements about their relative motion is
true after both of them started moving ?
Their relative velocity: (consider 1-D motion)
(A) first increases and then decreases
(B) first decreases and then increases
(C) is zero
MD) is non zero constant.​

Answer 1

Answer:

follow mate

Explanation:

Slope of a displacement time graph gives us velocity.

Here for both the children the graphs are straight lines (constant slope)

Hence both the children have constant velocities. But they are not equal (different slopes).

Hence relative velocity v

2

−v

1

=constant(nonzero)

Hence option D is correct
