Project 2: Learning goals
- Predict the motion of a single-particle system executing constant velocity or constant acceleration motion using appropriate representations (this includes verbal, graphical, diagrammatic, mathematical, and computational representations).
- Collect, analyze, and evaluate data to determine the type of motion and the properties of the motion of a single-particle system.
- Evaluate the applicability/limitations of models and the validity of predictions for different types of motion.
- Apply the momentum principle ($\Delta\vec{p}=\vec{F}\,\Delta t$; $d\vec{p}=\vec{F}\,dt$) iteratively/computationally to predict the motion or determine the properties of motion/net force acting on a single-particle system where the net force is not constant (e.g., due to spring-like restoring forces or dissipative drag forces).
Project 2: Learning issues
- Forces cause changes in momentum
- Kinematic Equations - Constant Acceleration
- Gravitational Force Near Earth
- Vector Components
- $\vec{F}_{net} = m\:\vec{a} = \dfrac{\Delta\vec{p}}{\Delta t}$
- Iterative Prediction of Motion
Project 2: Part A: Escape from ice station McMurdo
You are a member of a scientific research team at McMurdo ice station which is funded by the Carver Media Group in Antarctica.
Two members of your research team have recently returned from investigating an incident at a Norwegian research facility. They brought with them a burnt humanoid body with two faces. Since the disturbing discovery several inhabitants of the ice station have disappeared. Frightened, a member of your team decided to flee the station on a fan powered hovercraft but you receive a distress call not long after their escape that their steering and acceleration controls have been jammed and they need your help.
| Time | Your Team Member's Position | Your Position |
|---|---|---|
| 0 s | 2536.40 m | 10.47 m |
| 10 s | 3072.80 m | 41.88 m |
| 20 s | 3609.20 m | 94.22 m |
You decide to attempt a rescue in another hovercraft. You must decide how many members of your team help in the rescue operation. The hovercrafts do not have a velocity or acceleration gauge but they do have GPS locators and you possess your trusty stop watch. The GPS locator tells you the exact position of both your craft and other team members craft relative to the ice station. You are following their path. You collect the following data for the first 20 seconds of your journey.
You need to tell the runaway researcher the exact time from your starting time to jump onto your hovercraft as you may only have one shot at this rescue.
