Problem 5P

(a) Calculate the work done by gravity as a 5.2-kg object is moved from A to B in Figure along paths 1 and 2. (b) How do your results depend on the mass of the block? Specifically, if you increase the mass, does the work done by gravity increase, decrease, or stay the same? FIGURE

Step-by-Step Solution:

Solution 5P

Step 1 of 4

a)

The mass of the object is: .

While moving from A to B, the gravitational force and the displacement are perpendicular to each other.

As we know that, work done is the dot product of force and displacement vector, this will be zero while moving through the horizontal line.

Because the cosine of is zero which arises while calculating the dot product or the work done.
