Dimensional Analysis II

Date:

The density of Pb is 11.3 g/mL, what is the density in kg/L?

If a track star can run, 5.0 m in 1.0 seconds. How fast is this in miles per hour?

SPEED LABHow fast can you run in mph?

Mark and measure out a distance in the hall.

Time how long it takes you to run that distance.

Calculate your speed in miles per hour – show me the calculations in your notes.
