A sledge is pulled in a straight line by dogs, as shown.
The dogs produce a total horizontal driving force of 600 N.
The frictional force between the sledge and the surface is 150 N and the air resistance on the
sledge is 450 N. What is the resultant force acting on the sledge?
A 0 N B 300 N C 900 N D 1200 N

Answer:
Net Force is 0 N.
= 600N -[ 150N +450N ]
= 600N - 600N = 0
