Impact of debris, both natural and artificial, is a significant hazard for spacecraft. Space Shuttle windows are routinely replaced because of damage due to impact with small objects, and recent flights have employed evasive maneuvers to avoid impact with larger objects, whose orbits NASA constantly monitors. For the triangular shape window and the relative velocity of approach vE shown, determine the components and vector components of the velocity in directions normal and tangent to the window. Note that this information is needed before an analysis of damage due to impact can be performed.
