After 1.0 minutes, she arrives at the top of the hill, and her speed is now 7.0 m/s. What is her average acceleration in m/s^2?

You can put this solution on YOUR website!
Acceleration is (change in velocity)/(change in time)
\n" ); document.write( "\"%287+-+15%29%2F60\" m/sec2
\n" ); document.write( "\"-%288%2F60%29\"
\n" ); document.write( "\"-.1333\" m/sec2
\n" ); document.write( "This is a deceleration, or a negative accelertion
