The effort distance will be 160 cm.Applying the moment at the center as follows will provide the effort distance:
<h3 /><h3>What is the mechanical advantage?</h3>
Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtain the efficiency of forces in levers and pulleys.
Given data;
Effort,
Load,
Distance from the fulcrum,
The effort distance is found by applying the moment at the center as;
Hence, the effort distance will be 160 cm

Answer:
Retina is the part of eye which is used to see things in high details
For the part a) we need only the momentum of the box and we have the data to find it.
Momentum is given by,
where clearly, p is the momentum, m the mass of the box and v is the velocity.
Substituting,
For part b) we need an analysis of the situation. We understand that the box on a surface that has no friction will continue to rotate at the same speed previously defined. The box can only stop with friction, so,
<em>It is the same that part a)</em>
Answer:
Displacement. Units of measure metre (m)
Explanation:
Delta x Δx stands for displacement, or change in position.
