If a projectile is projected with initial velocity 98 m/s in a direction of 30^(@) above the horizontal. For this situation which one of the following is a correct statement ?

A body is at rest at x =0 . At t = 0 , it starts moving in the positive x - direction with a constant acceleration . At the same instant another body passes through x= 0 moving in the positive x - direction with a constant speed . The position of the first body is given by x_(1)(t) after time 't', and that of the second body by x_(2)(t) after the same time interval . which of the following graphs correctly describes (x_(1) - x_(2)) as a function of time 't' ?
