Algebra.Com's Answer #170741 by Alan3354(69443) You can put this solution on YOUR website! 1.) What is the speed of a bicycle that trvels 100ft. in 50 seconds at a constant speed? \n" ); document.write( "100 ft/50 sec = 2 ft/sec \n" ); document.write( "--------------------- \n" ); document.write( "2.)A car moving at a speed of 80 ft/s is stopped with a deceleration of 20ft/s/s. How long does it take to stop the car ? \n" ); document.write( "80/20 = 4 seconds. \n" ); document.write( "------------------ \n" ); document.write( "How far does the car go after the brakes are applied ? \n" ); document.write( "Since the acceleration is constant, the average speed for the 4 seconds is 1/2 the initial speed. \n" ); document.write( "4*40 = 160 feet \n" ); document.write( " \n" ); document.write( " |
