AB is A straight line of length 200 m. Particle P1 starts from A with initial velocity 11 m/s toward B and acceleration 11 m/ s2 toward B. After 5s its acceleration is changed to 15 m/s2 toward B. Particle P2 starts from B with iinitial velocity of 12 m/ s toward A and acceleration of 14 m/s2 toward A. After 3s it decelerates by 2 m/ s2. Particle P3 starts from a point at mid span of AB with a velocity 40 m/s toward B .and acceleration of 11 m/s2 toward A : Find when and where P1 will met P2- P1 will met P3 P2 will met P3 Solve using a-t, v-t and s-t diagrams (graphical) After that repeat solution using relations and physical equations Write a discussion for advantage and disadvantages of both methods
