Tom throws a football to Wes, who is a distance l away. Tom can control the time of flight t of the ball by choosing any speed up to v and any launch angle between 0◦ and 90◦. Ignore air resistance and assume Tom and Wes are at the same height. Which of the following statements is incorrect? Source: F=ma

Assuming the ball can reach Wes, as l increases with v held fixed, the minimum value of t increases. Assuming the ball can reach Wes, as v increases with l held fixed, the minimum value of t decreases. Assuming the ball can reach Wes, as l increases with v held fixed, the maximum value of t increases. Assuming the ball can reach Wes, as v increases with l held fixed, the maximum value of t increases.
