The initial distance between two particles is 300 m. The particles head towards each other at speeds of 1.5 m/s and 3.5 m/s, respectively. When will they meet? Where will the meeting take place? Plot the graph.

Answer

t = 60 s; x = 90 m

Explanation

The graph is shown in Fig. The law of motion is : `x_(1) =1.5 t , x_(2)= -300 +3.5t`.
