Dynamics: Projectile motion problem with incline (x/y axes are tilted)

Показать описание
We do the same problem again, but this time, we tilt our coordinate system such that the x axis is positive up the ramp, and the y is perpendicular to the ramp.

It gets fun, because now, the x-axis technically has an acceleration component
