Answer to Question #175792 in Physics for zoya

Question

The fastest growing plant on record is a Hesperoyucca whipplei that grew 3.7 m in 14 days. What was its growth rate in micrometers per second?

Answer 1

Divide the height by the time it took to grow this high:

$$v=\frac Ht=\frac{3.7}{14·24·60·60}=3.069·10^{-6}\text{ m/s}.$$

This is equivalent to 3.069 micrometers per second.
