Write the method drawSquare below. /** Precondition: 0 ≤ x < 10, 0 < y ≤ 10, and len > 0.

* Draws a square on a 10-by-10 xy-coordinate grid

* and prints the square’s side length and area.

* The upper left corner of the square will be located

* at the coordinate (x, y) and the side length of the

* square will be len (or as large as will fit in the grid).

public void drawSquare(int x, int y, int len)

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
