Problem:
Consider a particle with initial velocity v⃗ that has magnitude 12.0 m/s and is directed 60.0 degrees above the negative x axis.

What is the x component vx of v⃗ in meters per second?

Respuesta :

Example:

Suppose that a ball has an initial velocity v0 that has magnitude 20.0 m/s and is directed 60.0 degrees above the negative x axis.

Then, the x-component is,
20.0 * cos(-60) = 20.0 * (1/2) = 10.0 m/s
