To solve the problem we will apply the concepts related to the Intensity as a function of the power and the area, as well as the electric field as a function of the current, the speed of light and the permeability in free space, as shown below.
The intensity of the wave at the receiver is
The amplitude of electric field at the receiver is
The amplitude of induced emf by this signal between the ends of the receiving antenna is
Here,
I = Current
= Permeability at free space
c = Light speed
d = Distance
Replacing,
Thus, the amplitude of induced emf by this signal between the ends of the receiving antenna is 0.0543V
So the initial velocity is 15 m/s, the final velocity is 0 since it's at a complete stop and time is 10 seconds. Therefore:
Therefore, the acceleration is -1.5 m/s^2. The reason it's negative is due to the fact that the vector is going against it's original movement since it's decelerating.
