Explanation:
If a 1,500 kg car and a 4,000 kg truck were moving at the same speed down a steep hill, what statement is false?
A: The truck will have greater kinetic energy and be more difficult to stop.
B: The car has less mass, and therefore less kinetic energy, when compared to the truck.
C: Both vehicles would have their greatest kinetic energy as they reached the base of the hill.
D: The car's potential energy will be greatest when at its highest speed.
Answer:a
Explanation:because if you have a bigger or heavier truck I can be harder to stop then a car
The car kinetic energy not potential energy is greatest when at its highest speed.
Kinetic Energy:
It is the energy of the object which is due to the motion of object. The formula of kinetic energy is
[tex]\bold {KE = \dfrac 1{2} m v^2}\\[/tex]
Where,
m - mass
v - velocity
The kinetic energy of the object is directly proportional to the mass of the object and square of the velocity of the object.
So, A, B and C are correct statement.
Therefore, the car kinetic energy not potential energy is greatest when at its highest speed.

Answer:
First of all, scientific naming, also known as Biomial Numiclature, is a formal system of naming a specific species or living thing. We all use the scientific naming because we need to work together in most problems as a team and figure out what species an animal or species is.
Explanation:
Just so you know, if we never worked together, our goals would be a lot harder to accomplish. For example, I rn 7 miles yesterday with my mom. If my mom wasn't right there by my side while we were doing it, it would be a lot harder and I would've probably done a lot worse or less mileage.
Hope this helps!
