1. You've got a stubborn 180 kg donkey standing in the middle of a road. Let's call her Roberta.
Name the forces acting on Roberta. Draw a free-body diagram. Find the values of the forces.
2. You're trying to move Roberta now so you grab the reins and pull exactly horizontally with a
force of 10 N. She does not move. Name the forces acting on Roberta. Draw a free-body diagram.
Find the values of the forces.
3. You've got another stubborn 180 kg donkey a little farther down the road thatť's just standing
there. Let's call him Bob. The road slopes downhill at an angle of 10° from horizontal. Name the
forces acting on Bob. Draw a free-body diagram. Find the values of the forces.
4. You give up and go back to Roberta. You try pulling with 10 N again, but this time you pull at an
angle 13° below horizontal. Name the forces acting on Roberta. Draw a free-body diagram. Find
the values of the forces.
5. You now try and move Bob. You grab his reins and pull exactly horizontally with a force of 10 N
to get him to move down the hill. He does not move. Name the forces acting on Bob. Draw a
free-body diagram. Find the values of the forces.
6. You try pulling Bob with 10 N again, but this time you pull at an angle 8° above horizontal. Name
the forces acting on Bob. Draw a free-body diagram. Find the values of the forces.
7. You give up.
