A bowling ball is dropped from a bridge, and it takes 7 seconds to hit the ground. How far did the bowling ball fall?
To determine how far the bowling ball fell, we can use the formula for free fall distance:
d = 1/2 * g * t^2
Where:
d represents the distance
g represents the acceleration due to gravity (approximately 9.8 m/s^2 on Earth)
t represents the time in seconds
In this case, the time is given as 7 seconds. So we can substitute the values into the equation:
d = 1/2 * 9.8 m/s^2 * (7 s)^2
First, let's square the time:
d = 1/2 * 9.8 m/s^2 * 49 s^2
Now, we can multiply the acceleration due to gravity by the squared time:
d = 4.9 m/s^2 * 49 s^2
Finally, we multiply the two values together to find the distance:
d = 240.1 meters
Therefore, the bowling ball fell approximately 240.1 meters from the bridge.
