Question 4

A fly-fishing line is cast in a parabolic motion with an initial velocity of 30 meters per second at an angle of 60° to the horizontal and an initial height of 1 meter. The following parametric equations represent the path of the end of the line:

Revolt · Accepted Answer

To the nearest meter, the line travels a horizontal distance of meters.: 40; To the nearest tenth of a second, the end of the line reaches its maximum height after seconds.: 1.3
