Answer 1

The question involves using conservation of momentum and trigonometry to solve for unknown quantities in a two-dimensional collision in physics.

Step-by-step explanation:

The question appears to be related to the topic of momentum conservation and collision in physics, specifically involving trigonometric functions to solve for unknown quantities after a collision. The equations provided suggest a two-dimensional collision where momentum conservation applies separately in the x and y directions. Analyzing such a collision involves using the cosine and sine components of the velocities and applying the identity for the tangent function to solve for angles and velocities after the collision. This problem often requires a step-by-step approach to separate the horizontal and vertical components, equating them according to the law of conservation of momentum, and then solving for the unknowns using trigonometric ratios and inverse functions.
