Question 219069
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ v_f = v_o + at]


For this problem the initial speed is 30 m/s, and the final speed is 0.  Since the speed is expressed in meters per second, the time must be expressed in seconds.  One minute = 60 seconds, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0\ \text{\frac{meters}{second}} = 30\  \text{\frac{meters}{second}} + \left(a\ \text{\frac{meters}{second^2}}\right)\left(60\  \text{seconds}\right)]


Solve for *[tex \Large a], remember to pay attention to your units of measure, and check your answer for reasonability.
