Answer:
The two stoned hit the water after 2.92s after the first stone satat to drop
Explanation:
We have this data:
x = distance = 47.2m
So = initial speed = 1.8m/s
A = In this case is equal to gravity = 9.8 m/s2
First we are going to calculate the final speed, We are going to use this equation
Where Sf= final speed
We put the data
We need to calculate the square root
The final speed is 30.47m/s
The next steep is calculate the time that the first stone spend during its drop.
We are going to use the next equation
We put tha data
We do not use 0.8s because we calculate all the things with the first stone, This stone spend more time that the second stone
