A motorboat is speeding at 12.3 m/s through a group of periodic ocean waves. When the motorboat travels in the same direction as the waves, it smashes into 6.5 waves per minute. When the motorboat travels in the opposite direction to the waves, it smashes into 34 waves per minute.

(a) Calculate the speed of the ocean waves.
m/s

(b) Calculate the frequency of the ocean waves.
Hz

(c) Calculate the wavelength of the ocean waves.
m

For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). a) Measurements of the blood flow in the ascending aorta shows a maximum speed of 92.00 cm/sec. Assuming the ultrasound frequency used is 2.000000 MHz (the paper uses 2.25 MHz), calculate the frequency as seen by the blood that is traveling toward the ultrasound transducer at 92.00 cm/s. The transducer, which both transmits and receives the sound...

A speeding motorist zooms through a 50 km/h zone at 75 km/h (21 m/s) without noticing a stationary police car. The police officer immediatley heads after the speeder, accelerating at 2.5m/s^2. When the officer catches up to the speeder, how far down the raod are they, and how fast is the police car going? I know you use the equations x= x_0+ v_0t+ .5at^2 and v= V_0 + at... But I want to know why we use these equations and...
