Question : Two cars 𝐴 and 𝐵 at rest at same point initially. If 𝐴 starts with uniform velocity of 40 𝑚/𝑠𝑒𝑐 and 𝐵 starts in the same direction with constant acceleration of 4𝑚/𝑠 2 , then 𝐵 will catch 𝐴 after how much time

(A) 10 𝑠𝑒𝑐

(B) 20 𝑠𝑒𝑐

(D) 35 𝑠𝑒c

Answer : option (B)

Solution :

Two cars 𝐴 and 𝐵 at rest at same point initially. If 𝐴 starts with uniform velocity of 40 𝑚/𝑠𝑒𝑐 and 𝐵 starts in the same direction with constant acceleration of 4𝑚/𝑠 2 , then 𝐵 will catch 𝐴 after how much time
