| Algebra.Com's Answer #276593 by mananth(16946)     You can put this solution on YOUR website! If you start at rest and accelerate to a speed of 100 miles per hour in 12 seconds, how fast will your acceleration be?\r \n" ); document.write( "\n" ); document.write( "... \n" ); document.write( "Convert mph to ft/sec \n" ); document.write( "100 mph = 100*5280/3600 \n" ); document.write( "= 146.66 ft/s \n" ); document.write( ".. \n" ); document.write( "v= u+at \n" ); document.write( "v = final velocity \n" ); document.write( "u = initial velocit \n" ); document.write( "t= time= 12 seconds \n" ); document.write( "146.66= 0+a*12 \n" ); document.write( "divide by 12 \n" ); document.write( "146.66/12 = a \n" ); document.write( "12.22 ft/s^2 \n" ); document.write( "... \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
