Algebra.Com's Answer #436719 by josgarithmetic(39630) ![]() You can put this solution on YOUR website! At the start your speed is 0 km/hr. After moving and accelerating for 5 seconds your speed is 60 km/hr. Acceleration is [change in rate] divided by [change in time]. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Here the units are changed first to seconds instead of hours, but your purposes may justify not other time units.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(60 km/hour) * (1 hour/60 min) * (1 min/60 sec) = 1/60 km/sec\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Look at the data. \n" ); document.write( "final rate = 1/60 km/sec \n" ); document.write( "initial rate = 0 km/sec \n" ); document.write( "final time = 5 sec \n" ); document.write( "initial time = at 0 sec\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Acceleration = \n" ); document.write( "= |
