a.
Answer to Problem 67E
The required time for which the fish has to swim away is 0.97 seconds.
Explanation of Solution
Given information:
The initial height,
The initial vertical velocity,
Formula used:
Calculation:
The initial height is
The initial vertical velocity is
To find the required time, use the equation
Substitute
To solve the above equation for t , use the formula
Solve for t .
Now,
And,
But time cannot be negative.
Hence, the required time for which the fish has to swim away is 0.97 seconds.
b.
To determine: The bird which will reach the fish first.
