What is the time of flight for a projectile each of these following cases? gravity is acting in the negative y-direction. 6. a. a ball is thrown at 0° from the horizontal. it lands at ax= 6m, ay =-3m. b. a ball is thrown at 30° from the horizontal. it lands at ax =10m, ay=om. c. a ball is thrown at 600 from the horizontal. it lands at ax= 3m, ay=4m.
