Answer:
8 Newtons
Step-by-step explanation:
Net force is the vector sum of forces acting on a particle or body. It can also be regarded as a single force replaces the effect of the original forces on the particle's motion.
We calculate the net force, which is the the vector sum of all forces acting on an object
Given
F, norm = 20N
F, grav = 20N
F,app = 22N
F, frict = 14N
The net force here as stated earlier is calculated as sum of upward and forward forces minus sum of downward and backward forces.
So, Net force = (F, norm + F,app) - (F, frict + F, grav)
Substitute each value
Net force = (20N + 22N) - (20N + 14N)
Net force = 42N - 34N
Net force = 8N
Hence, the net force on the object is 8 Newtons
