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?

Verified Answer :

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
