Question
In order to find the depth of a well, you drop a stone into it and time its fall. It hits the water after falling for 1.7 s. The depth of the well is about Question 17Answera.20mb.14mc.28md.10me.5m
Solution
To find the depth of the well, we can use the physics formula for distance fallen under gravity, which is d = 0.5 * g * t^2, where g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth) and t is the time the stone was falling.
Step 1: Substitute the given values into the formula. In this case, t = 1.7 seconds.
Step 2: Calculate the depth (d) using the formula.
d = 0.5 * 9.8 * (1.7)^2
Step 3: Calculate the value.
d = 0.5 * 9.8 * 2.89
d = 14.205 meters
So, the depth of the well is approximately 14 meters. Therefore, the answer is b.14m.
