11. Momentum & Impulse Elastic Collisions
4PRACTICE PROBLEM
An alpha particle moves at a speed of 4.50 × 10 6 m/s due north. The alpha particle collides elastically with a neon atom initially at rest. Taking the neon atom to be 5 times the mass of the alpha particle, determine the velocity (magnitude and direction) of the particles after the collision. Take the initial direction of the alpha particle as positive.
