AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A body of mass \(3 \mathrm{~kg}\) is moving with a velocity of \(8 \mathrm{~ms}^{-1}\) collides head on with another body of mass \(1 \mathrm{~kg}\), moving in the opposite direction with a velocity of \(4 \mathrm{~ms}^{-1}\). After the collision, if the two bodies stick together and move, they move with a common velocity
- A \(5 \mathrm{~ms}^{-1}\)
- B \(7 \mathrm{~ms}^{-1}\)
- C \(10 \mathrm{~ms}^{-1}\)
- D \(14 \mathrm{~ms}^{-1}\)
Answer & Solution
Correct Answer
(A) \(5 \mathrm{~ms}^{-1}\)
Step-by-step Solution
Detailed explanation
Given, mass, \(m_1=3 \mathrm{~kg}\) Velocity, \(v_1=8 \mathrm{~ms}^{-1}\) Mass of another body, \(m_2=1 \mathrm{~kg}\) Velocity of another body, \(v_2=4 \mathrm{~ms}^{-1}\) After collision, both bodies stick together and move with a common velocity, applying conservation of…
