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.

Answers

Answer 1

Answer:a

Explanation:because if you have a bigger or heavier truck I can be harder to stop then a car

Answer 2

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.

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!

what would happen if 15 joules of work is done on an object that has 90 N of force applied to it

Answers

Answer:

The magnitude of the force is given by F = ma = (10)(5) = 50 N. It acts over a distance of 20 m, in the same direction as the displacement of the object, implying that the total work done by the force is given by W = Fx = (50)(20) = 1000 Joules.
