Which of the following best defines the definition of a Newton (N)? *
0/1
The amount of force that would give a mass of one kilogram an acceleration of one meter per second per second
Kg * m/s².
Both answers above are correct.
A cookie with a fig fruit filling
One Newton can be defined as the amount of force that would give a mass of one kilogram an acceleration of one meter per second per second.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
A spring balance can be used to calculate the Force. Newton is the SI unit of force.
From Newton's second law of motion: we know that:
Force = mass × acceleration
Now in SI system:
Unit of force is Newton.
Unit of mass is kg and unit of acceleration is meter per square second.
Hence, one Newton force can be defined as:
The required force to generate 1 meter per square second acceleration on an object of mass one kilogram.

A ball accelerates uniformly at +4.0 m/s2
If the ball was initially moving a +0.20 m/s and the average velocity was +4.2 m/s, then how long will it take it to reach the final velocity?
It will take 1 second to reach the final velocity
Acceleration of a body is the change in velocity of the body with respect to time. This is mathematically represented as;
[tex]a=\frac{v-u}{t}[/tex]
Given the following parameters
a = +4.0 m/s²
u = +0.20m/s
v = +4.2m/s
Substitute the given parameters into the formula to get the time "t"
[tex]4=\frac{4.2-0.2}{t}\\4t=4.2-0.2\\4t=4.0\\t=\frac{4}{4}\\t=1sec[/tex]
This shows that it will take 1 second to reach the final velocity

A murder has been committed and you are a juror at the trial. The prosecuting attorney has presented evidence that the victim put up a struggle and injured her assailant, drawing blood, prior to her demise. Blood typing was completed and the blood type matches the defendant's blood type. The prosecuting attorney states that this evidence is proof that the defendant is guilty of murder. As a juror, do you think the defendant is guilty of murder based on this evidence? Why or why not? If not, what other evidence do you think is needed?
The fact that the blood type matches that of the defendant is no proof that the defendant is guilty as charged.
There are about four blood types that people can have, these blood types are; A, B, AB and O. Everybody must posses one of these blood types. A person's blood type is determined through laboratory tests.
The prosecuting attorney was wrong in concluding that the defendant is guilty as charged only based on the blood type evidence. different people could have the same blood type. Only DNA analysis can conclusively prove that the defendant is actually guilty as charged.

Explanation:
The forces act on skateboard when we push it are , external force of 500N and friction force because of the surface.
What is the Newton's First law of motion?The stationary object will remain stationary or the subject in the motion will keep its motion until or unless the external force is not applied .
What will happen when we apply 500 N external force to the skateboard?We know the only force which is going to oppose the applied 500N force is the friction force due to surface.First as we will apply the external force the skateboard and the box will start gaining the velocity and the accelerationAfter some time because of the friction force the skateboard and the box will start losing its velocity because of the friction force and the combined mass they are having and at the end it will stop moving forward. it is also depends on their mass also.If we put different types of objects on the skateboard then the time period of lost of velocity will be different .If we put object having more mass then the combined system (skateboard + object ) will start losing its velocity quickly . and visa versa for the object having less mass.So, by the Newton's first law of motion we can understand this concept.

Determine the horizontal component of applied force on the mower:
Fx=__N (round to 3 digits)
Determine the horizontal frictional force acting on the mower
Ff=__N (Round to 3 digits)
Calculate the applied force the person must exert on the mower for it to accelerate at a rate of 1.00m/s^2
