Question

Оторвавшаяся от крыши сосулька падает с балкона 4 этажа с высоты 13 м. Какую скорость она будет иметь на высоте 2 м?

Answer 1

V0=0, h1-h2=v2/2g,  v2=h1-h2/2g,
  v=0.74м/с

Answer 2

Calculation of the Speed of the Falling Icicle

To calculate the speed of the falling icicle at a height of 2 meters, we can use the principles of free fall motion. The speed of an object in free fall can be determined using the equation:

v = √(2gh)

Where: - v is the speed of the object - g is the acceleration due to gravity (approximately 9.8 m/s² on Earth) - h is the height from which the object falls

In this case, the height from which the icicle falls is 13 meters. So, we can substitute these values into the equation to find the speed of the icicle at a height of 2 meters.

v = √(2 * 9.8 * 13) m/s

Calculating this equation gives us:

v ≈ 16.04 m/s

Therefore, the icicle will have a speed of approximately 16.04 m/s when it reaches a height of 2 meters.
