Question

One drops a penny from the top of a tall building onto the ground below. The height of the building is 443 m. How long will it take for the penny to hit the ground?

Answer 1

It will take approximately 9.14 seconds for the penny to hit the ground.

Step-by-step explanation:

To determine how long it will take for the penny to hit the ground, we can use the equation for free fall: h = 1/2 * g * t^2. In this equation, h represents the height of the building, g represents the acceleration due to gravity (approximately 9.8 m/s^2), and t represents the time it takes for the penny to hit the ground. Solving for t, we have:

t = sqrt(2 * h / g)

Plugging in the values for h (443 m) and g, we can calculate t:

t = sqrt(2 * 443 / 9.8) = 9.14 seconds

Therefore, it will take approximately 9.14 seconds for the penny to hit the ground.
