Question

A 0.15 kg glider moving 0.80 m/s collides elastically with 0.30 kg glider moving -2.20 m/s. Find final velocities.
Options
A 3.2 m/s and 0.50 m/s
Correct Answer
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

Option A is the correct answer.

Detailed Explanation

Use conservation of momentum and kinetic energy for elastic collisions.

Hint

m1u1 + m2u2 = m1v1 + m2v2.
