Problem

A projectile is launched with an initial speed of

20\,\text{m/s}

at an angle of

30^{\circ}

relative to an inclined plane. The incline itself makes an angle of

30^{\circ}

with the horizontal. Determine the range of the projectile along the inclined plane. (Take

g = 10\,\text{m/s}^{2}

)
