Shown in the figure are the velocity time graphs of the two particles P 1 and P 2 . Which of the following statements about their relative motion is true?
Their relative velocity: (consider 1-D motion)
Text Solution
Verified by ExpertsThe correct answer is:
D
Slope of v – t graph = acceleration
v 1 = a 1 (t –t 0 ) = tan θ 1 t – tan θ 1 t 0
v 2 = a 2 (t – t 0 ) = tan θ 2 t – tan θ 2 t 0
v r = v 1 – v 2 = (tan θ 1 – tan θ 2 ) t – t 0 (tan θ 1 – tan θ 2 )
So v r continuously increases.
