The skull is designed to protect the brain.
Chloroplasts are organelles specialized for photosynthesis. Animals do not photosynthesize; therefore, they do not need chloroplasts.

Given that the two trucks have the same mass but different velocities, that is truck A is traveling 15 km/h and truck B is traveling 30 km/h, hence Truck B will have a greater stopping distance.
The reason why Truck B will have a greater stopping distance is because it speed is greater hence more distance to cover.
From the following expression
Speed = Distance/Time
Distance = Speed*Time
More on the kinetic Energy
Following from the given problem truck B will also have more kinetic energy because it velocity is more
Formula
KE= 1/2mv^2
Hence the more the velocity for a constant mass the greater the Kinetic energy
