Question

Тело Свободно падает с высоты 45 м.Чему равно время падения тела? (g=10 м/с) ?​

Answer 1

Ответ:

H=45 Если нет начальной скорости H=gt^2/2 g=10м/c^2

45=10t^2/2

10t^2=90

t^2=9

t=3 cек

Answer 2

Time of Free Fall

To calculate the time of free fall for an object, we can use the formula:

t = sqrt(2h/g)

Where: - t = time of free fall - h = height from which the object falls - g = acceleration due to gravity (approximately 10 m/s^2)

Substituting the given values: - h = 45 m - g = 10 m/s^2

We can calculate the time of free fall using the given formula:

t = sqrt(2*45/10) t = sqrt(9) t = 3 seconds

Therefore, the time of free fall for the object is 3 seconds.
