A man pulls a 10kg chair across the floor with a force of 20N directed at 30degrees. what is horizontal force?

0 ⤊

And assuming no friction, what is the acceleration?

Horizontal Force = 20 x cos30
=0.866N

Acceleration assuming there is no Friction= 0.866 / 10
=0.0866ms^(-2)

I assume it is 30 degrees with the horizontal.

Fh= Fcos(30)
a=Fh/m= Fcos(30)/m
a=20 cos(30) /10=1.73 m/s^2
