JEE Main Physics question

A body is at rest at . At , it starts moving in the positive -direction with a constant acceleration. At the same instant another body passes through moving in the positive -direction with a constant speed. The position of the first body is given by after time and that of the second body by after the same time interval. Which of the following graphs correctly describes as a function of time [AIEEE 2008]

• (A)A curve starting at the origin, dipping negative, then rising back through zero and curving upwardCorrect
• (B)A curve starting at the origin and rising directly (always positive, concave up)
• (C)A curve that stays below the axis throughout
• (D)A curve that is a mirror image of (A), dipping positive first then falling
