40. A box slides to the right across a horizontal floor. A person called Ted exerts a force

T

to the right on the box. A person called Mario exerts a force

M

to the left, which is half as large as the force

T

. Given that there is friction

f

and the box accelerates to the right, rank the sizes of these three forces exerted on the box. (A)

f<M<T

(B)

M<f<T

(C)

M<T<f

(D)

f=M<T
