The equations of motion to use for a constant acceleration a = g = -9.81:


at the highest point the velocity must be zero:

combine both equations:

Solve for v₀:
I think it is building and managing of irrigation systems
Answer:
Increasing until terminal velocity is reached
Explanation:
Provided the scream is a constant pitch at the source, Doppler effect will make the pitch increase as the velocity of the source towards the listener increases.
