1.Draw position-time graphs for two objects having zero relative velocity.2.An object is in uniform motion along a straight line. What will be position- time graph for the motion of the object ifa)x0=+ve,v=+veb)x0=+ve,v=-vec)x0=-ve,v=+ved)x0=-ve,v=-veThe letters x0 and v represent postion of the object at t=0 and uniform velocity of the object respectively.3.Two ends of a train moving with a constant acceleration passes a certain point with elocities u and v. Show that the elocity with which the middle point f the train passes the same point is square root of(u2+v2)/2.
