Today's nonsense
- Fire alarms going off (can't hear them in Gardner's room).
- Phoebe's overuse of exclamation points in email
- Homework due today.

If you have different forces, you have to combine the forces.

From the homework: 11) A tugboat tows a ship with constant force F and in 10 seconds it increases in velocity at 4 km/h. Change in velocity over change in time is acceleration. Essentially, here, you combine the vectors and figure out how the second force compares to the first by knowing the mass and using that with F_1 and (F_1+F_2) data.

Worked on the semilog graph paper.
