Smooth Incline Problem (2 Viewers)

[iLearn4U]

A body of mass m is pulled up a smooth incline making an angle of theta with the horizontal, and has an acceleration f.

Find the force that pulls the body.

I get the answer as F=mf+mgsin(theta) but the book answer is F=m(f+sin(theta)

Where did the g go?

It must be a typo, since your answer with g is correct.
