Question

Нач.скорость тела при свободном падении равна 15 м/с, ускорение свободного падения принять равным 10 м/с². Какой путь будет пройден телом за 3 часа?

Answer 1

Есть формула h=(V0)t-gt(2)/2 минус потомучто он вверх летит отсюда(V0)=15м/с если перевести в км/ч то будет 54 км/ч t=3ч h=54×3-10×3(2)/2=117км

Answer 2

Calculation of the Distance Traveled by an Object in Free Fall

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

distance = initial velocity * time + (1/2) * acceleration * time^2

Given the following information: - Initial velocity (u) = 15 m/s - Acceleration due to gravity (g) = 10 m/s² - Time (t) = 3 hours

We need to convert the time from hours to seconds, as the formula requires time to be in seconds.

1 hour = 3600 seconds

Therefore, the time (t) in seconds is: t = 3 hours * 3600 seconds/hour = 10800 seconds

Now, we can substitute the values into the formula to calculate the distance traveled:

distance = 15 m/s * 10800 s + (1/2) * 10 m/s² * (10800 s)^2

Simplifying the equation:

distance = 15 m/s * 10800 s + (1/2) * 10 m/s² * 116640000 s²

distance = 162000 m + 583200000 m

distance = 583362000 m

Therefore, the object will travel a distance of 583,362,000 meters in 3 hours.
