Now we're working in 2 dimensions.
There are two main types of problems:
- Crosswinds or 'cross river' type problems
- Projectile motion problems

Below: In "projectile motion" problems, we separate the 'x' and 'y' components and solve them separately using the 5 equations of motion.
Projectile Motion lab (Ballistics lab)
We will fire a projectile at different angles, measuring the flight time, distance, and vertical drop.
From these, we can estimate the acceleration of gravity, 'g'.

Surveying Lab (alternate lab)
Outdoor surveying lab: Vectors
We will use commercial surveying equipment (transit-level) to determine the distance of a far-away object (more than 1 mile away) using nothing but angles and vector measurements.
Then we will compare our calculated distance with Google Earth to see how close we came.
If we do this carefully, you may be surprised at how close we come to the 'actual' distance.
