An eagle is flying horizontally at a speed of 4.8 m/s when the fish in her talons wiggles loose and falls into the lake 7 m below. Calculate the speed of the fish relative to the water when it hits the water.

Expert Solution

Given that initially, the eagle holding the fish is flying horizontally at 4.8m/s

So the fish will have an initial horizontal velocity the same as the eagle when it gets loose.

Initial horizontal velocity of fish,

Initial vertical velocity of fish,

Initial height of the fish,

--------

Consider the vertical motion of the fish.

Use formula

--------------

Consider the horizontal motion of the fish

There is no acceleration in the horizontal direction, so horizontal velocity remains the same.

-------

Final velocity,

An eagle is flying horizontally at the altitude of 400 ft with a velocity of 16 ft/s when it drops a dead prey. A frog jumps 2 seconds later at a site facing away from the eagle and 60 ft from the point beneath the original position of the bird. If the frog catches the falling prey at the height of 144 ft, determine the initial speed and angle of inclination of the frog. Please use an advanced math way...

An airplane flying in the air with a constant velocity of 240 m/s horizontally experiences a force due to gravity, directed downwards with a magnitude of 4×10^6 N, and a force generated by the engines, directed forwards with a magnitude of 3 × 10^6 N. a. In light of Newton’s first law, why must there be a third force acting on the airplane? Calculate the magnitude of this third force, and explain its physical origin. Draw this third force on...

A bug flying horizontally at 0.85 m/s collides and sticks to the end of a uniform stick hanging vertically. After the impact, the stick swings out to a maximum angle of 5° from the vertical before rotating back. If the mass of the stick is 10 times that of the bug, calculate the length of the stick.

When serving, a tennis player hits the ball horizontally. With a speed of 29.12 m/s. What minimum height, H (in m) from which the ball must be launched to just clear the 0.90 m high net about L = 17.65 m from the server. How far from the end of the service box (which is a distance of S = 6.80 m from the net) will the ball land if it just clears the net? Use the positive direction if...
