The true anomaly of a trajectory with this shape with respect to time can be found from Barker’s equation. (15[1]-5[1])The proposal of flight with this shape to simulate zero-gravity was (15[1])hypothesized (15[2])by the Haber brothers, (15[4]-5[1])leading to the (15[2])development (15[1])of NASA’s “Vomit Comet.” (15[6])Perfect (15[1])orbits (-5[1])with this shape (15[1])while (15[1])hypothetically possible don’t exist in nature because of the necessity of traveling (15[1])at an object's (15[1]-5[1])exact escape (15[1]-5[1])velocity. (15[2])(*) Mirrors with (10[1])this two (10[1])dimensional (10[1])shape (10[2])can collimate light from a (10[1])point (10[1])source (10[1])or send (-5[1])straight parallel rays to a common focus point. Galileo (-5[1])gave instructions on how (10[1])to draw (-5[1])one of these shapes in Two New (10[1])Sciences, in which (-5[1])he also notably demonstrated a certain motion had this shape. For 10 points, name this shape of the trajectory of classical projectile motion. ■END■ (10[9]0[1])
