Question

Тело опущенное с некоторой высоты без начальной скорости падало в течении 9 секунд. Какова скорость тела?

Answer 1

Дано t=9c   V- ?

V=g*t=10*9=90 м/с

Answer 2

V=V0+gt, V0=0, V=9,8м/с^2*9c=90м/с, это большая скорость и падение с вертолета(с очень большой высоты); 90м/с=324 км/ч

Answer 3

Calculation of the Speed of a Falling Object

To calculate the speed of a falling object, we can use the equation of motion for free fall:

v = g * t

Where: - v is the final velocity (speed) of the object - g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth) - t is the time taken for the object to fall

In this case, the object falls for 9 seconds. We can substitute the values into the equation to find the speed:

v = 9.8 m/s^2 * 9 s

Calculating this, we find that the speed of the object is approximately 88.2 m/s.

Please note that this calculation assumes that there is no air resistance affecting the object's fall.
