====================================


Formula will be



$f \times s \ \times cos(60)$





$we \: know \: that \: \cos(60) = \frac{1}{2}$

$so \: further \: solving \: work \: done \: will \: be \:$





$\frac{f \times s}{2}$

Answer 2

W=Fdcostheta
if cos theta =60°
then we know that cos 60=1/2

so simply put in equation

W=Fdcos(60)
W=Fd(1/2)

W=Fd/2
Half of work is done
