Question

4) Speedy shoots another arrow at an angle of 45 degrees at speed (according to him) 0.5c, while riding in Wonder Woman's invisible plane, going at v=0.75c relative to his friend Terra as shown.

A) What angle from the horizontal does Terra say the arrow is flying?

B) If the speeds of the plane and arrow were nonrelativistic (say 5.0x10-4c and 7.5x10-4c), what angle would she report (use ordinary Galilean relative velocity transformations)
