Question: Two bodies of masses 0.1 𝑘𝑔 and 0.4 𝑘𝑔 move towards each other with the velocities 1 𝑚/𝑠 and 0.1 𝑚/𝑠 respectively, After collision they stick together. In 10 𝑠𝑒𝑐 the combined mass travels

(A) 120 𝑚

(B) 0.12 𝑚

(D) 1.2 𝑚

Answer: Option (D)

Solution:

Two bodies of masses 0.1 𝑘𝑔 and 0.4 𝑘𝑔 move towards each other with the velocities 1 𝑚/𝑠 and 0.1 𝑚/𝑠 respectively, After collision they stick together. In 10 𝑠𝑒𝑐 the combined mass travels
