Problem

A projectile is launched with speed

50\,\text{m/s}

at an angle of

30^{\circ}

relative to a

30^{\circ}

incline. Calculate the magnitude of the change in velocity vector

|\Delta \vec{v}|

between the launch point and the point of impact on the incline. (Take

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

)
