Answer:
So, this is not the answer because I suck like that (hehe >:3) but here's some helps.
Explanation:
1. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below.
2. If the net force acting on an object is zero, then the object is not accelerating, and is in a state known as equilibrium.
3. This will be were you use the info I gave to figure it out. I hope this wasn't completely unhelpful.

Answer:
6ms^-1
Explanation:
Given that the frequency difference is
( 563- 544) = 19
So alsoThe wavelength of each wave is = v/f = 344 /544
and there are 19 of this waves
So it is assumed that each motorcycle has moved 0.5 of this distance
in one second thus the speed of the motorcycles will be
=> 19/2 x 344/544 = 6.0 m/s
