29. Three students, A, B, and C, have designed a projectile launcher to hit a target on the ground. They launch the projectile from level ground at a speed of 10 m/s at an angle of 30 to the horizontal, but the projectile travels only halfway to the target before hitting the ground. Which of the students is correct on how they should adjust their projectile launcher to hit the target? A. Student A says that they should increase the launch speed to 20 m/s and keep the angle the same. B. Student B says they should increase the angle of launch to 60 and keep the launch speed the same. C. Student C says they should increase the launch speed to 14 m/s and keep the angle the same. D. None of the students is correct
