I just did the assignment and got it correct hope this helps
When the temperature is higher, molecules will speed up and bump into each other causing them to spread farther apart. Therefore, the density is less. This is the opposite when the temperature is cooler.
The kinetic energy of an object that has a mass of 50.0 kg and a velocity of 18m/s is 8,100J.
<h3>KINETIC ENERGY:</h3>
Kinetic energy refers to the energy of a body due to its motion. The kinetic energy can be calculated as follows:
K.E = ½ m × v²
Where;
- K.E = kinetic energy (J)
- m = mass (kg)
- v = velocity (m/s)
According to this question, an object that has a mass of 50.0 kg and a velocity of 18m/s. The kinetic energy can be calculated as follows:
K.E = ½ × 50 × 18²
K.E = ½ × 16,200
K.E = 8100J.
Therefore, the kinetic energy of an object that has a mass of 50.0 kg and a velocity of 18m/s is 8,100J.

By definition, Newton's First Law, also called the Law of inertia, indicates that "Every body perseveres in its state of rest or of uniform rectilinear motion unless it is forced to change its state by forces impressed on it."
This means that for a body to come out of its state of rest or of uniform rectilinear motion, it is necessary for a force to act on it.
<h3>Definition of inertia</h3>
So, in other words, all bodies are opposed to changing their state of rest or motion and this opposition is called inertia.
<h3>Body in equilibrium</h3>
In this way, a body is in equilibrium when the resultant of the forces acting on it is zero. That is, it is not possible for a body to change its initial state (be it rest or motion) unless one or more forces intervene.
