A neon atom (m=20.0u) makes a perfectly elastic collision with another atom at rest. After the impact, the neon atom travels away at a 40.0 ? angle from its original direction and the unknown atom travels away at a -50.0 ? angle.

Part A

What is the mass (in u) of the unknown atom? [Hint: You can use the law of sines.]

A moving ball (ball #1) makes a perfectly elastic collision with a stationary ball (ball #2)....

A moving ball (ball #1) makes a perfectly elastic collision with a stationary ball (ball #2). After the collision it is observed that the speed of ball #2 is five times that of ball #1. Determine the angles θ1 and θ2 that the two balls scatter as measured from the initial direction of ball #1. You may assume that the two balls have identical masses, and you may need the identity sin2(x) + cos2(x) = 1. Please explain any concepts...
