I have a real world problem...

• model > evaluate > solve
• solve > model > evaluate
• solve > evaluate > model
• model > solve > evaluate > model > solve > evaluate > model > ...

No friction on a surface

• inextensible
• rough
• smooth
• light

A light object...

• might float
• has negligible mass
• will break
• has no centre of mass

A uniform body

• mass is distributed evenly and acts at the centre
• always wears a blazer
• has neglible mass
• not effected by resistive forces

5 km/hour

• 5000×60×60 m/s
• 25/18 m/s
• 5000/(60×60) m/s
• (60*60)/5000 m/s
