**Dynamics Help. My exam is on Monday!!!**

My Dynamic's Unit Exam is on Monday and I need help! Last week I had my Kinematic's Unit Exam and my written was something like:

How do you find the acceleration of a runner running the 100m sprint? Draw a sketch, list all the formulas you're going to use, do a sample calculation (make up some reasonable numbers), and a brief discussion of where some errors could occur.

My teacher said my Dynamic's written will be exactly the same thing, but I need help because how do I measure the force, power, kinetic energy, etc, using "classroom" type materials? We never did any labs.

Please help, I'll really appreciate it.
