NEET Physics Angular Momentum MCQ Question
Consider a diagram showing two particles undergoing an elastic collision in a two-dimensional plane. Particle 1 has mass m1 and initial velocity v1i at an angle θ1 with respect to the x-axis. Particle 2 has mass m2 and is initially at rest. After collision, particle 1 moves with velocity v1f at angle θ1' and particle 2 with velocity v2f at angle θ2. Which set of equations would you use to solve for the unknown final velocities and angles?
Conservation of linear momentum in x and y directions and conservation of kinetic energy.
Only conservation of linear momentum in the x-direction.
Conservation of angular momentum and kinetic energy.
Conservation of linear momentum in x and y directions only.
Correct Answer
Detailed Explanation
For an elastic collision in two dimensions, conservation of linear momentum in both the x and y directions and conservation of kinetic energy are used to solve for final velocities and angles.
