Question

You drving in car 1 and your friend is drving in car 2 playing music at a frequency f. Van V is also driving on the same road.

1) Write an equation for the frequency you will hear generated by your friend and bounced off the van. Express the frequency you heard in terms of f.

v car 1 = 100.0 km/h

v car 2 = 80.00 km/h

v van V = 60.00 km/h

V
