An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.335 m above his mouth. What is the minimum speed at which the archer fish must spit?

A boat crosses a river of width 225 m in whichthe current has a uniform speed of 1.35 m/s.The pilot maintains a bearing (i.e., the direction in which the boat points) perpendicularto the river and a throttle setting to give aconstant speed of 2.92 m/s relative to the water.What is the magnitude of the speed of theboat relative to a stationary shore observer?Answer in units of m/s. How far downstream from the initial positionis the boat when it reaches the opposite shore?Answer in units of m

A projectile is fired from a cliff 190 feet above the water at an inclination of 45 degree to the horizontal ,with muzzle velocity of 45 feet per second. The height h of the projectile above the water is given by h(x)=-32x^2/((45)^2) +x+190 Where x is the horizontal distance of the projectile from the face of the cliff. (A) At what distance from the face of the cliff is the height of the projectile a maximum?
