Answer: No work is done on the bag in the process
Explanation:-
Work is defined as the the force resulting into displacement of an object.
[tex]w=f\times s\times cos\theta[/tex]
w = work done
f = force exerted
s = displacement
[tex]\theta=90^0\\cos(90^0)=0[/tex]
[tex]w=f\times s\times 0=0[/tex]
As, the direction of force is upward but the motion of the room is horizontal , thus the angle made is [tex]90^0[/tex]. Hence the work done is zero.
Thus work done is 0 joules.
The workdone is 0 joules, this shows that no work is done on the bag in the process
Work is said to be done if the force applied to an object causes the object to move over a distance.
The formula for calculating the workdone is expressed as:
[tex]W=F\times d cos \theta[/tex]
Note that the distance is [tex]dcos \theta[/tex] since the body moves in a horizontal direction. The direction is also perpendicular showing that [tex]\theta =90^0[/tex]
Substituting into the formula:
[tex]W = Fdcos 90^0\\W=Fd(0)\\W=0Joules[/tex]
Since the workdone is 0 joules, this shows that no work is done on the bag in the process
