Given the speed and the distance, to find time you can use the formula speed is equal to distance over time. From there you can manipulate the equation for time to equal the distance divided by speed. Time is equal to 18.4 meters divided by 35m/s which equals 0.526 seconds.
The two balls separate but continue to move in the same direction
Answer:
Explanation:
Given
altitude of the Plane 
When Airplane is 
away
Distance is changing at the rate of 
From diagram we can write as
differentiate above equation w.r.t time
as altitude is not changing therefore 
at 
substitute the value we get 
The answer to your question would be C
