Question

Two gliders collide elastically: 0.15 kg at 0.80 m/s and 0.30 kg at 2.20 m/s opposite direction. Final velocities?
Options
A 3.2 m/s and 0.50 m/s
B 1.0 m/s and 2.0 m/s
C 32 m/s and 20 m/s
D 0.2 m/s and 3.2 m/s
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Applying conservation of momentum and kinetic energy gives approximately 0.2 m/s and 3.2 m/s.

Hint

Elastic collision → momentum and KE conserved.
