Answer to Question #261182 in Physics for cutie

Question

Two forces act on a 2-kg box. The first force is 10 N to the right, while the second force if 5 N to left. Determine the resultant acceleration.

Answer 1

The resultant force is

$$F_\text{net}=F_1-F_2=10-5=5\text{ N}.$$

The acceleration:

$$a=F_\text{net}/m=10/2=2.5\text{ m/s}^2.$$
