Learning Goal:Once you have decided to solve a problem using Newton's 2nd law, there are steps thatwill lead you to a solution. One such prescription is the following:• Visualize the problem and identify special cases.• Isolate each body and draw the forces acting on it.• Choose a coordinate system for each body..Apply Newton's 2nd law to each body.• Write equations for the constraints and other given information.• Solve the resulting equations symbolically.• Check that your answer has the correct dimensions and satisfies specialcases.• If numbers are given in the problem, plug them in and check that the answermakes sense.• Think about generalizations or simplifications of the problem.As an example, we will apply this procedure to find the acceleration of a block of mass m2that is pulled up a frictionless plane inclined at angle with respect to the horizontal by amassless string that passes over a massless, frictionless pulley to a block of mass m₁ thatis hanging vertically. (Figure 1)Visualize the problem and identify special casesFirst examine the problem by drawing a picture and visualizing the motion. Apply Newton's 2nd law, F = má, to each body in your mind. Don't worry about which quantities are given. Think about the forces oneach body: How are these consistent with the direction of the acceleration for that body? Can you think of any special cases that you can solve quickly now and use to test your understanding later?One special case in this problem is if m₂ =0, in which case block 1 would simply fall freely under the acceleration of gravity: a₁ = -gjPart AConsider another special case in which the inclined plane is vertical (0 = π/2).

Also assign a symbol to the mass of the block and label it on the drawing. 2. Draw a free-body diagram of the forces on the block as it slides down the ramp. Draw the acceleration vector for the block near the free-body diagram. Choose a coordinate system, and draw the force vectors on your coordinate system (a force diagram).
