Solving MA: Sum of Forces = Mass x Acceleration

In summary, the formula for solving MA: Sum of Forces = Mass x Acceleration is F = m x a, where F represents the net force, m represents the mass, and a represents the acceleration. The value of the net force can be determined by adding all the individual forces acting on an object, while the mass can be measured in kilograms and the acceleration can be calculated by dividing the change in velocity by the change in time. The units for the variables in the equation are Newtons (N) for force, kilograms (kg) for mass, and meters per second squared (m/s^2) for acceleration. This equation can be used for any type of motion, and it is significant because it allows us to understand and predict

Sum of forces = MA

The Attempt at a Solution



I already found the answer to part A, which is 10kg. But for part B I am not sure which box to draw my FBD on.

Since you want the acceleration of body A, analyze the forces on body A.

I would first start by defining the problem and identifying the known and unknown variables. In this case, the problem is to determine the mass of the object, given the equation Sum of Forces = Mass x Acceleration. The known variables are the sum of forces and the acceleration, and the unknown variable is the mass.

Next, I would draw a free body diagram (FBD) to represent the object and all the forces acting on it. This will help me visualize the problem and determine which box to draw the FBD on. In this case, I would draw the FBD on the object itself, and label all the forces acting on it, such as gravity, normal force, and any applied forces.

From there, I would use the equation Sum of Forces = Mass x Acceleration to set up an equation and solve for the unknown variable, which in this case is the mass. By rearranging the equation, I can solve for the mass by dividing the sum of forces by the acceleration. This will give me the mass of the object.

In conclusion, as a scientist, I approach problem solving by first defining the problem, identifying known and unknown variables, drawing a visual representation of the problem, and then using equations and mathematical methods to solve for the unknown variable.
