First, create an illustration of the motion of the two cars as shown in the attached picture. The essential equations used are:
For constant acceleration:
a = v,final - v,initial /t
d = v,initial*t + 1/2*at²
For constant velocity:
d = constant velocity*time
The solutions is as follows:
a = v,final - v,initial /t
3.8 = (v₁ - 0)/4.6 s
v₁ = 17.48 m/s
Total distance = d1 + d2 + d3
d1 = d = v,initial*t + 1/2*at²
d2 = constant velocity*time
Total distance = 0*(4.6) + 1/2*(3.8)(4.6)² + (17.48)(9.2) + d3= 257.71
d3 = 56.69 m

Answer:
.
Explanation:
Intensity of the electromagnetic radiation is given by
where is the distance from the EM source (the center of the sun, in our case), and
is the power output of the sun and it has the value
Since the radius of the sun in meters is , the intensity
of the electromagnetic radiation at the surface of the sun is
The intensity of the electromagnetic radiation at the surface of the sun is .
