Question

The net force acting on this object is 200N to the left. What is the force of friction and air resistance combined if the thrust force is 500N?

Answer 1

Step-by-step explanation:

Force of friction and air resistance acts against the external force . Let it be f .

net force = external force - frictional force and air resistance

Putting the given values

200 = 500 - f

f = 500 - 200 = 300 N .

Hence force of friction = 300 N .
