Question

Мяч свободно падает с балкона в течение 2 с .На какой высоте находится балкон?

Answer 1

4см если я не ошибаюсь

Answer 2

H=(gt^2)/2=(10*4)/2=20 м

Answer 3

Calculation of the Balcony Height

To determine the height of the balcony, we can use the equation of motion for free fall. The equation is:

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

Where: - h is the height - g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth) - t is the time in seconds

Given that the ball falls freely for 2 seconds, we can substitute these values into the equation to find the height of the balcony.

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

Calculating this, we find:

h = 19.6 meters

Therefore, the balcony is located at a height of approximately 19.6 meters.
