Question

look at the diagram below. determine the net force acting upon the object. a 6 n, up b -6 n c 5 n, left d 15 n

Explanation:

Step1: Analyze vertical forces

The normal force $F_{norm}=3\ N$ acts upwards and the gravitational force $F_{grav}=3\ N$ acts downwards. The net - force in the vertical direction $F_{net - y}=F_{norm}-F_{grav}=3 - 3=0\ N$.

Step2: Analyze horizontal forces

The frictional force $F_{frict}=5\ N$ acts to the left. There is no other horizontal force. So the net - force in the horizontal direction $F_{net - x}=F_{frict}=5\ N$ to the left.

Step3: Calculate the net force

Since the net - force in the vertical direction is 0 N and the net - force in the horizontal direction is 5 N to the left, the net force acting on the object is 5 N to the left.

Answer:

C. 5 N, left
