Question

to the
1.
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)
(1) first increases and then decreases
(2) first decreases and then increases
(3) is zero
(4) is non zero constant​

Answer 1

Answer:

4

Explanation:

Slope of a displacement time graph ( position-time and displacement-time are exactly the same thing )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 V2 - V1=constant(nonzero)

Hence option 4 is correct
