The total time for car to travel the given distance is 2 s.
<h3>
Time of motion of the car</h3>
The time of motion of the car is determined by applying second kinematic equation as shown below;
where;
- v is the constant speed = 6m/s
- t is the time of motion = ?
- a is the acceleration = 1.5 m/s²
- s is the distance traveled by the car = 15 m
Thus, the total time for car to travel the given distance is 2 s.

<span>Przykro mi, ale nie podałeś zdjęcia problemu, o który pytasz, i nie mówię po polsku, który wydaje się być twoim językiem, ale używam tłumacza, kocham ciebie i twoich ludzi i życzę miłego dnia .</span>
hey,
I'm here to help
just multiply each mouse's velocity components
then,
add them all up to get x,y total
According to Gauss' law, the electric field outside a spherical surface uniformly charged is equal to the electric field if the whole charge were concentrated at the center of the sphere.
Therefore, when you are outside two spheres, the electric field will be the overlapping of the two electric fields:
E(r > r₂ > r₁) = k · q₁/r² + k · q₂/r² = k · (q₁ + q₂) / r²
where:
k = 9×10⁹ N·m²/C²
We have to transform our data into the correct units of measurement:
q₁ = 8.0 pC = 8.0×10⁻¹² C
q₂ = 3.0 pC = 3.0×10<span>⁻¹² C
</span><span>r = 5.0 cm = 0.05 m
Now, we can apply the formula:
</span><span>E(r) = k · (q₁ + q₂) / r²
= </span>9×10⁹ · (8.0×10⁻¹² + 3.0×10⁻¹²) / (0.05)²
= 39.6 N/C
Hence, <span>the magnitude of the electric field 5.0 cm from the center of the two surfaces is E = 39.6 N/C</span>
