## Homework Statement

A car traveling at 60 mi/h stops in 6 seconds. How far does it travel during this time?

## Homework Equations

a=Δv/Δt

x=xinitial+vinitialt+1/2(a)t^2

## The Attempt at a Solution

First I changed units into the standard ones:

60 mi/h *1609.34 m/1 mi * 1 h/3600 s = 26.8223 (the 3 seemed to be repeating.)

Then I used a=Δv/Δt, assuming the Vinitial was zero:

26.8223/6

a≈4.47 m/s^2

Finally, I plugged my numbers into this equation:

x=xinitial+vinitialt+1/2(a)t^2

and got 80.46 m.

Would someone please check that this is correct?
