Question

Тіло кинуте вертикально вниз без початкової швидкості.Час падіння 6 сек Знайти висоту падіння та швидкість тіла при ударі об землю?​

Answer 1

Ответ:

180 м     60 м/с

Объяснение:

t=6 c    h=?    v=?

===

h=g*t²/2=10*6²/2=180 м

v=g*t=10*6=60 м/с

Answer 2

Calculation of the Height of Fall

To calculate the height of the fall, we can use the formula for the distance traveled by an object in free fall:

h = (1/2) * g * t^2

Where: - h is the height of the fall - g is the acceleration due to gravity (approximately 9.8 m/s^2) - t is the time of fall

Given that the time of fall is 6 seconds, we can substitute these values into the formula:

h = (1/2) * 9.8 * 6^2

Calculating this expression, we find:

h = 176.4 meters

Therefore, the height of the fall is 176.4 meters.

Calculation of the Velocity at Impact

To calculate the velocity of the object at impact, we can use the formula for the final velocity of an object in free fall:

v = g * t

Where: - v is the final velocity at impact - g is the acceleration due to gravity (approximately 9.8 m/s^2) - t is the time of fall

Given that the time of fall is 6 seconds, we can substitute these values into the formula:

v = 9.8 * 6

Calculating this expression, we find:

v = 58.8 m/s

Therefore, the velocity of the object at impact is 58.8 m/s.

Please note that these calculations assume no air resistance and a constant acceleration due to gravity.
