shown in the diagram at the
right). Another worker then fills
the bucket with bricks until the
total mass of the bucket is 96 kg.

Analysis and Questions:
1. Set the parameters as follows: vo = 0, k = 0.4000, s = 0.5000, g = 9.810 m/s2, m = 5.000 kg.
Predict: In order to keep the block at rest on the incline plane, the angle of the incline plane
can’t exceed what value? Draw a free body diagram of the block and show your calculation.
2. Set the angle to your predicted value (keep proper significant figures otherwise it will affect
your simulation result). Does the simulation result match your prediction? If it doesn’t, redo your
calculation and modify your answer to question 1. Keep testing until the simulation result
matches your prediction.
3. Will increase or decrease the mass of the block affect your prediction to question 1? Explain.
A person pushes a box along the ground. The box has the force diagram shown below. Examine the force diagram to answer the following questions:
a. Is the box in equilibrium? If so explain how you can tell. If not, explain why not.
b. If the person wants the box to move at constant velocity, should they adjust their pushing on the block? If so, explain how they should change their push. If not, explain why they should change nothing about their push
