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 graph correctly describes as a function of time?

• (A)A curve rising directly from the origin, curving upward, staying non-negative throughout
• (B)A similar upward-curving, non-negative curve from the origin
• (C)A curve starting at the origin, dipping below the axis (negative) to a minimum, and then curving back up through zero into positive valuesCorrect
• (D)Another non-negative upward-curving variant
