Explanation:
Let us assume the mass of ship 2 = K
Mass of ship 1 = 4K
Condition:
Both ships have the same mass
The kinetic energy of a body is the energy due to the motion of it.
It is expressed as:
K.E =
m is the mass of the ship
v is the velocity;
Since both ships have equal velocity;
K.E of ship 1 = K.E of ship 2
\frac{1}{2} m v^{2} of ship 1 = \frac{1}{2} m v^{2} of ship 2
multiply through by 2;
4k x = k x
dividing by k;
4 v_{1} ^{2} = v_{2}^{2}
taking square root of both sides
V₂ = 2V₁

Since the mirror is plane, the image will be formed behind the mirror. The distance will be the same as that of the distance of the object from the mirror and the height will just be the same.
So, Ruff's image will be 3 m behind the mirror and 50 cm tall.
Thunderstorms might form on warm days simply because heat is what causes evaporation, causing rain. Thunderstorms also form when the atmosphere is unstable! Meaning the hot air is above the cold air, evaporation occurs, it rains, and then rapid expansion of heat in the air caused by lighting causes thunder.
