Answer:
Moment of the 4N force = 16Nm
Moment of the 6N force = 12Nm
Explanation:
Find the diagram attached.
Moment of a force is the product of the force and the perpendicular distance from the point of application
For the 4N force
Distance of the force from O is 4m
Moment of the 4N force = 4N * 4m
Moment of the 4N force = 16Nm
For the 6N force
Distance of the force from O is 2m
Moment of the 6N force = 6N * 2m
Moment of the 6N force = 12Nm
Newton's first law is called inertia, or the force an object has to resist unbalanced forces that are placed upon it. The more mass an object has, the more inertia an object has. The less mass an object has, the less inertia an object has.
Force is mass into acceleration
and pressure is force applied per unit area.
Answer:
The initial velocity is 12.34[m/s]
Explanation:
To understand this problem, let's draw a sketch of what is happening. In the attached image we can fin de sketch.
According to the equations of uniform movement accelerated we have to express them in the two components x and y.
In this problem we will analyze first the movement in the y axis and its equation to obtain the velocity in the initial point (o) and then with the angle of 33° respect to the horizontal we can find the main velocity.
In the previous equation we have the negative term - (2*a*y), the reason for the negative sign is because gravity is the acceleration that is acting downwards.
Therefore:
Now with the velocity in the y component, we can calculate the main vector of the velocity.
The main topic to understand in this problem is that when the height is maximum the velocity will be zero in the y component, therefore Vy=0 and we can simplify the problem.
