Answer:
Explanation:
Given
mass of Projectile(m)=0.46 kg
Initial Kinetic Energy=1430 J
Maximum upward displacement from Launch point=150 m
v=78.85 m/s
and 
initial horizontal velocity
Initial vertical velocity
(c)vertical velocity at any instant=65 m/s
Since initial vertical velocity is 54.16 m/s
so 65 m/s will be acquired when projectile started falling below cliff
As you approach the police car with blaring siren, you hear a change in pitch and frequency. The apparent pitch changes as a result of the Doppler effect. Frequency determines pitch; frequency and wavelength are inversely proportional. You wouldn't "hear" either one. The result is pitch.
