A river has a width d. A fisherman in a boat crosses the river twice. During the first crossing, his goal is to minimize the crossing time. During the second crossing, his goal is to minimize the distance that the boat is carried downstream. In the first case, the crossing time is T 0 . In the second case, the crossing time is 3T 0 . What is the speed of the river flow? Find all possible answers.An aircraft is .flying. horizontally with a constant vefocity =200m//s at a height =1km above groun At the momement shown, a bomb is released from the aircraft and the cannon-gun below fires a shell with initial speed =200m//s , at some angle theta For what value of theta will the projectile shell destroy the bomb in mid-air? If the value of theta is 53^(3) , find the minimum distance between the bomb and the shell as they fly past each other. Take sin53^(@)=4//5-duplicate-1
