Question

Тело падает с высоты 490 м, определите его скорость в момент падения на землю

Answer 1

10с,98 м/с момент падения на землю

Answer 2

Calculation of the velocity of an object falling from a height of 490m

To determine the velocity of an object falling from a height of 490m, we can use the equation of motion for free fall. The equation is:

v = √(2gh)

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

Substituting the given values into the equation, we have:

v = √(2 * 9.8 * 490)

Calculating this expression, we find that the velocity of the object at the moment it hits the ground is approximately 98 m/s.

Please note that this calculation assumes no air resistance and that the object is falling near the surface of the Earth.
