Expert Answer

Step 1

Given information:

Mass of the body (M) = 10 kg

The forces acting on the body:

Step 2

From the diagram the force in the “x direction” are as follows:

Fx = FBcos30 + FAcos60 …… Equation (1)

According to Newton 2nd law the acceleration and net external force can be related as:

F = ma

Hence, we can write the as:

Max = FBcos30 + FAcos60
