PRACTICE / Dimensional analysis
What units belong to a restoring coefficient?
A force magnitude follows F = c x², where displacement x is measured in metres. The coefficient c has numerical value 8 in SI units.
What force acts at x = 0.50 m?
Organize the givens & assumptions
- c = 8 N/m²
- x = 0.50 m
Use the stated quadratic force-magnitude model over the given displacement range; c has units N/m².
- A
- B
- C
- D
