Question

tommy pushes his truck with 8 n of force to the left along the carpet. the carpet resists the motion of the truck with 6 n of force to the right.
what is the net force acting on the truck in newtons?
8 n to the left
6 n to the right
2 n to the left
14 n to the right

Explanation:

Step1: Define force directions

Let left - direction force be positive, so the applied force \( F_1 = + 8\space N\) (to the left), and the resistive force \( F_2=- 6\space N\) (to the right, opposite to left).

Step2: Calculate net force

The net force \( F_{net}=F_1 + F_2\). Substitute the values: \( F_{net}=8+( - 6)=8 - 6 = 2\space N\). Since the result is positive, the net force is in the left direction.

Answer:

2 N to the left
