p = mv so this question pertains to conservation of momentum.
The momentum of the car is 1320*12 = 15840kgms^-1
For the sake of easiness and the fact negatives are annoying, I will assume east to be positive.
So we know 9.4m - 15840 = (1320+m)*1.5
9.4m - 15840 = 1980+1.5m
Rearranging to solve for m
7.9m = 17820
m = 2255.70 = 2300kg to 2sf

Explanation:
We have the following data:
is the speed of the water wave
is the frequency of the water wave
Now, the speed of a wave is given by the following equation:
Where is the wavelength.
Isolating :
Finally:
This is the water wave wavelength
