Question

Two forces of 60 N east and 30 N west act on a 300kg mass. if friction is neglected, what is the resulting acceleration of the mass?

Answer 1

Net force is

$$\bold{F=F_1+F_2}$$

$$F=F_1-F_2=60-30=30\ N$$

directed eastwards.

The resulting acceleration of the mass:

$$a=\frac{F}{m}=\frac{30}{300}=0.1 \frac{m}{s^2}$$

directed eastwards.
