Question 6 8 pts At time t = 0, a projectile is launched from ground level and travels in a symmetric parabolic path over flat ground. The projectile hits the ground at time t = 8 s. If the magnitude of the projectile's horizontal velocity was 25 m/s at time t = 7 s, what was the magnitude of its horizontal velocity at time t = 3 s? O 45 m/s 15 m/s 65 m/s O 25 m/s 0 5 m/s
