Question

A stone is dropped down a well and hits the water 2.50 s later. What is the depth from the edge of the well to the water?

A) 30.6 m
B) 61.3 m
C) 12.3 m
D) 2.50 m

Answer 1

The depth from the edge of the well to the water is approximately 30.6 m.

Step-by-step explanation:

To calculate the depth from the edge of the well to the water, we can use the equation d = 1/2 * g * t^2, where d is the depth, g is the acceleration due to gravity, and t is the time. In this case, the time is given as 2.50 seconds. The acceleration due to gravity is approximately 9.8 m/s^2. Plugging these values into the equation, we get:

d = 1/2 * 9.8 * (2.50)^2 = 30.625 m

Therefore, the depth from the edge of the well to the water is approximately 30.6 m.
