A machine fired several projectiles at the same angle, e, above the horizontal. Each projectile was fired with a different initial velocity, vi. The graph below represents the relationship between the magnitude of the initial vertical velocity, Viy, and the magnitude of the corresponding initial velocity, v; of these projectiles. Determine the angle, , above the horizontal at which the projectiles were fired. A. 39° B. 35° C. 33° D. 40°
