Motion in Straight Line
Question
Wired Faculty App

A body starts from x0 = 5m with velocity u = 10 m/s and B body starts from x0' = 10 m and with velocity u' = 5 m/s. Can we find when and where A will overtake B from graph? Explain.

Answer

For body A,

Initial distance, xo = 5 m
Initial velocity, u = 10 m/s 

For body B, 

Distance,xo' = 10 m 
velocity, u' = 5 m/s

From the graph, point where the position time graphs of two bodies meet, corresponds to position and time where the A will overtake B.
