( Question 9 of 1'." ) Danielle launches a ball off of a platform of height h with velocity Be at an angle 6 above the horizontal. A wall with a ballsized hole a height H above the oor. with H > h. is a horizontal distance L = 27.5 m away from Danielle. The dierenee in height between H and h is onetwelfth of L, and Macmillan Learning the square of the magnitude of the velocity. Hg. is x; \\:. threehalves of the product g]... 1 HhziL 12 3 03:5gL Determine the two values of 6' that ensure the ball passes through the hole. Submit the larger angle as 6' and the smaller angle as 93. m A camera operator is lming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to his campsite. By watching debris owing down the river. the operator estimates that the stream is owing at 0.625 mfs. In still water. the explorer can swim at 0.731 mfs. At what angle. less than 90. with respect to the shoreline should the operator advise him to swim so that he travels directly across the stream to his campre? The water is near freezing in temperature. Typically a human can only swim in such water for about 300 s (or 5 min) before Macmillan Learnin P1 \\9 hypothermia sets in. Calculate the time the explorer spends in the water if the river is 29.1 n1 wide. Based on the results. what should the camera operator's decision be about the explorer's swim? 0 Approved. He will get cold but he should be able to make it across. 0 Sorry. but the swim must be cancelled. He will never make it across in time
