An outfielder on the opposing team starts running at 7.60 m/s the instantthe ball is hit. Calculate the farthest the fielder can be from where the ball will land so that it is possiblefor him to catch the ball, i.e. distance between fielder’s original position and lading of the ballA baseball batter hits a long fly ball, giving it an initial velocity 45.0° above the horizontal. The ball risesto a maximum height of 14.8 m. An outfielder on the opposing team starts running at 7.60 m/s the instantthe ball is hit. Calculate the farthest the fielder can be from where the ball will land so that it is possiblefor him to catch the ball, i.e. distance between fielder’s original position and lading of the ball. [HINT: Assume that the outfielder catches the ball at the same height at which it was hit, and that hebegins running at the same time that it was hit.]
