Answer:
22600 cm³ (3 s.f.)
Explanation:
Please see the attached picture for the full solution.
To solve this problem we will apply the definition of Newton's second law, which says that force is equivalent to body mass by acceleration. In this case the mass of the trailer is 325Kg and its acceleration is
, so we will proceed to replace and multiply these values to find the net force on this object.


F= 698.75N
Under the reference system in which the direction of travel is the positive direction, the direction of the force will be positive.
The wave frequency is 2 Hz.
What is wave frequency ?
The number of waves that pass through a fixed point in a given amount of time is referred to as the wave frequency. The hertz is the SI unit for wave frequency (Hz).
