Can we use SONAR for finding the speed of the submarine, if it were moving underwater ?

How can we change the speed and the direction of a moving body?

How is a sonar used in finding the depth of the sea-bed?

A SONAR system fixed in a submarine operates at a frequency40.0 kHz. An enemy submarine moves towards the SONAR with a speed of 360km h^(-1) .What is the frequency of sound reflected by the submarine? Take the speed of sound in water to be 1450ms^(-1)
