three men are trying to move a skip. Two of the men are pushing horizontally with forces of magnitude 120N and 150N and one man is pulling with a horizontal force of magnitude XN. The frictional force resisting the motion is 385N. Given that the skip does not move, find the value of X.

Answer:

115 N

Explanation:

There are multiple forces acting on the skip, so we must first look at the directions the forces are acting in.

The men who are pushing and pulling the skips are all applying force in the same direction, while friction is resisting them, so it is getting applied in the opposite direction.

Since the skip does not move, this means that the forces are balanced.

So we must add all the forces and equate them to 0.

Assuming that the direction that X is being applied in is +ve, we get the following:

120 + 150 + X - 385 = 0

Solving this, we get:

X + 270 = 385

X = 115 N
