Calvin is standing on the roof of a 6.50 m tall house. His tiger Hobbes is on the ground, some distance away from the house. Calvin is throwing water balloons at Hobbes: Calvin is throwing the water balloons with speed VO at an angle of 0 below the horizontal. On his first try, Calvin hits Hobbes with the water balloon! Hobbes is 3.02 m horizontally from the base of the building and it takes 1.04 s for the balloon to hit him. Coordinate system: positive x points to the right and positive y points up.
Sam fields a baseball hit to him in the left field. He then throws the ball to third to force out the base runner, Mike. Sam releases the ball 1.75 m above the ground with a vertical velocity of 8.5 m/s and a horizontal velocity of 26.5 m/s. At the instant Sam releases the ball, he is 43 m from the third baseman, Charlie, and Mike is 14 m from third base and running at 8.5 m/s toward third. Assume that air resistance does not affect the flight of the ball when answering the following questions. a. How high in the air does the ball go? b. How much time does it take for the ball to reach the third baseman? c. How high is the ball when it reaches the third baseman? d How long does it take Mike to reach third base if he maintains his 8.5 m/s pace?
