Ответ: Швидкість тіла в момент падіння на поверхню землі можна визначити за допомогою формули для рівномірно прискореного прямолінійного руху:

v = √(2 * g * h)

де v - швидкість тіла, g - прискорення вільного падіння (приблизно 9,8 м/с²), h - висота, з якої падає тіло.

Підставляючи відповідні значення, отримаємо:

v = √(2 * 9,8 м/с² * 0,8 м) ≈ √(15,68 м²/с²) ≈ 3,96 м/с

Отже, швидкість тіла в момент падіння на поверхню землі приблизно дорівнює 3,96 м/с.
