Answer:
500 Ns
Explanation:
According to the impulse theorem, the change in momentum of an object is equal to the impulse exerted on it. Mathematically:
where
is the change in momentum of the object
I is the impulse exerted, which is the product of
F, the net force exerted
, the time interval during which the force is applied
In this problem,
F = 100 N is the force applied on the wagon
is the time interval
Substituting, we find the change in momentum of the wagon:
Answer:
Newton's third law of motion.
Explanation:
An ice skater at rest pushes against a sled at rest,causing both the skater and sled to move away from each other with different acceleration. It is based on Newton's third law of motion.
Third law says that, for every action there is an equal; and opposite reaction. Here, action is force applied by ice skater and reaction is motion of skater and sled away from each other with different acceleration.
Answer:
16.6N
Explanation:
Given parameters:
Mass of rocket = 2000g = 2kg
Acceleration = 8.3m/s²
Unknown:
Force acting on the rocket = ?
Solution:
The force acting on a body can be derived from the product of its mass and acceleration;
Force = mass x acceleration
Insert the parameters and solve;
Force = 2 x 8.3 = 16.6N
Answer:
because they could cause harm to others
Explanation:
The "First Amendment" gives people the right to freedom of: <em>religion, expression, press and assembly. </em>However, the government has the right to censor one's speech<u><em> if it could cause harm to others.</em></u> Such speech falls under "unprotected category." This category includes the following: <em>Defamation, Perjury, Blackmail, Plagiarism, True Threats, Child P.ornography, Obscenity, Solicitations to Commit Crime, Fighting Words, Incitement of Imminent Lawless Action.</em> These forms of speeches are meant to harm other people, thus, they are not protected by the First Amendment.
