Homework Statement


Convert 83km/hr to m/s^2


Homework Equations


Simple I know...but I still can't figure it out


The Attempt at a Solution


83km/hr(10^3m/km)(1hr/60min)(1min/60sec)

The units cancel however leaving me with m/s not with m/s^2.

The seconds^2 is what I cannot figure out.

Thanks in advance!

You can't convert km/hr to m/s^2.
 
83 km/hr is not acceleration, it is a speed. Your answer is right. Are you sure that is what they want?
 
Yah, m/s^2 is an acceleration, km/hr is a velocity. Must be a typo
 
Peng, isn't it supposed to be speed instead of velocity? Velocity has a specified direction.
 
Really? Must be a typo then...good to know that I'm not missing something obvious!

Sigh...

Doesn't matter. Don't troll.
