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 𝑥1(𝑡) after time 𝑡 and that of the second body by 𝑥2 (𝑡) after the same time interval. Which of the following graphs correctly describes (𝑥1 − 𝑥2 ) as a function of time 𝑡?

Question : 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 𝑥1(𝑡) after time 𝑡 and that of the second body by 𝑥2 (𝑡) after the same time interval. Which of the following graphs correctly describes (𝑥1 − 𝑥2 ) as a function of time 𝑡?

(A)

(B)

(C)

(D)

Answer : option (B)

Solution :

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 𝑥1(𝑡) after time 𝑡 and that of the second body by 𝑥2 (𝑡) after the same time interval. Which of the following graphs correctly describes (𝑥1 − 𝑥2 ) as a function of time 𝑡?
