Question : A particle moving along a straight line has a velocity 𝑣 ms−1 , when it cleared a distance of 𝑦 meter. These two are connected by the relation 𝑣 = √49 + 𝑦. When its velocity is 1 ms −1 , its acceleration (in ms −2 )

(A) 1

(B) 2

(D) 0.5

Answer : option (D)

Solution :

A particle moving along a straight line has a velocity 𝑣 ms−1 , when it cleared a distance of 𝑦 meter. These two are connected by the relation 𝑣 = √49 + 𝑦. When its velocity is 1 ms −1 , its acceleration (in ms −2 )
