Work = force x displacement
W = 25 x 2
W= 50 J

Answer:

C). W = 50 J

Explanation:

As we know that the work done is the product of force and displacement

so here it is given that the net force on the stack of books is 25 N

\(F = 25 N\)

also the displacement of the stack of books is 2m as it is lifted upwards

so we have

\(d = 2 m\)

now by the formula of work done we know

\(W = F.d\)

now plug in all values in it

\(W = (25)(2)\)

\(W = 50 J\)
