Homework Help: Science

Posted by Becca on Friday, September 30, 2011 at 4:49pm.

The problem I'm trying to answer is:
Ann is driving down a street at 59 km/h.
Suddenly a child runs into the street.
If it takes Ann 0.719 s to react and apply
the brakes, how far will she have moved before
she begins to slow down?
Answer in units of m.

I know the first step is to convert 59 km/h to m/s, but I'm not sure how. I know how to solve the problem after ward. Can someone show me and explain the formula I would need to use for this problem? Thank you!
