The depth of the lake is 500 meters.
According to the question
Acceleration = 10 m/s²
Time = 10 sec
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
The distance covered in a certain time of accelerated motion:
D = (1/2) × A × T²
Distance covered= (1/2) (Acceleration) (Time squared) .
The question gives us the acceleration and the time.
Let's plug them into the formula.
Distance = (1/2) (10 m/s²) (10 sec)²
= (5 m/s²) (100 sec²)
= 500 meters.
The depth of the lake is 500 meters.
