A student uses a force of 45 Newtons to push a chair at a constant speed of 3m/s for a time of 6 seconds how much work did the student do?
Clara Nights
W = F*d
d = 3m/s * 6s = 18m
W = 45N18m = 810Nm

What are 5 examples of unbalanced forces?
Anything that is accelerating or decelerating because it is only balanced when something is moving at a constant speed.
What is the force at sea level that a boy of 50 kg exerts on a chair in which he is sitting?
Its weight is 490.3N (about 110.2 pounds).
When a force of 15 newtons is applied to a stationary chair it starts moving What can you say about the frictional force between the chair and the floor of the room?
If it starts moving, that implies that the frictional force is less than 15 N.
What does newtons third law say about forces?
Newton's Third Law of Motion states that for every force there is an equal, opposite, and co-linear force countering the original force. An example of this would be the force of you, sitting in a chair, pressing down on the Earth, being balanced by an equal and opposite force of the Earth pressing up on you and the chair. Answer2: At Conservation of Energy, the forces sum to zero.
What is the difference between a cantilever chair and a normal chair?
The difference between a cantilever chair and a normal chair is that a cantilever chair is easier movable and more flexible. The chair is however more expensive, but for the features it gives it is worth it.

Is sitting in a chair an example of newtons first law of motion?
yes. the 1st law of motion states that's an object will remain at rest or constant motion unless an external unbalanced force acts on it.
What happens when someone pushes a chair across the room using newtons second law of motion?
The chair movement is dependent on its weight and the amount of force
What does a student say when he trips over his chair at school?
oops
How often does Newton's third law of motion happen?
Always. Evey object in the universe is experiencing Newtons third law. Just by sitting in your chair motionless you are experiencing Newtons third law.
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
How many minutes does it take to load one chair at 200 chairs in 180 minutes?
54 seconds per chair.
Which Newtons law of motion can explain what happens when someone pushes a chair across the floor?
It will have no equilibruim and when you are pushing it you are using a force

Its weight is 490.3N (about 110.2 pounds).
What does a teacher do if a student gets stuck in a classroom chair?
If a students gets stuck in a classroom chair the teacher must find out where the student is stuck and try to remedy it. If the teacher cannot get the student in the teacher should get the assistance of the principal, custodian or even the fire department if that is necessary. The teacher must make sure that the student does not get harmed while trying to free the student.
