A person on the ground threw a ball at the rate 3 ft/s. The ball reached the peak of its trajectory 5 seconds after they threw it. Which of the following is incorrect? (Ignore the height of the person.) O The velocity of the ball at its peak is 0. O The velocity of the ball just before it hits the ground is also 3 ft/s due to symmetry. O The total time of flight is 10 seconds after they threw it. O The ball will take 5 seconds to fall from its peak to the ground.
