An athlete wants to estimate the pressure she exerts on the track when standing stationary on one foot. She records the following measurements in a table:
| Measurement | Value |
|---|---|
| Her weight | 550 ............ |
| Area of the track in contact with her shoe | 220 cm2220 \text{ cm}^2220 cm2 |
Complete the table by writing the correct unit for weight on the dotted line.
State the name of a piece of equipment that the athlete could use to measure her weight.
Suggest a method the athlete could use to find the contact area of her shoe on the track.
State the formula linking pressure, force, and area.
Calculate the pressure, in N/cm2\text{N/cm}^2N/cm2, that her shoe exerts on the track.
