AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A body of mass \(5 \mathrm{~kg}\) makes an elastic collision with another body at rest and continues to move in the original direction after collision with a velocity equal to \(\frac{1}{10}\) th of its original velocity. Then the mass of the second body is
- A 4.09 kg
- B 0.5 kg
- C 5 kg
- D 5.09 kg
Answer & Solution
Correct Answer
(A) 4.09 kg
Step-by-step Solution
Detailed explanation
Mass of the first body \(m_1=5 \mathrm{~kg}\), for elastic collision \(e=1\). Suppose initially body \(m_1\) moves with velocity \(v\) after collision velocity becomes \(\left(\frac{u}{10}\right)\). Let after collision velocity of \(M\) block becomes \(\left(v_2\right)\). By…
