Algebra.Com's Answer #828695 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! 1.A long jumper at 20' angle and attains a maximum height of 0.6 m. How far is her jump? \n" ); document.write( "---------------- \n" ); document.write( "It's a parabola.\r \n" ); document.write( "\n" ); document.write( "2. A car starts from rest with an acceleration of 8 m/s². After 30s, how fast is it going? \n" ); document.write( "---- \n" ); document.write( "8*30 = 240 m/sec \n" ); document.write( "===================== \n" ); document.write( "3. A bag is dropped from cliff 50m high Disregarding air resistance, how long does it take it to reach ground? \n" ); document.write( "---- \n" ); document.write( "s = at^2/2 \n" ); document.write( "50 = at^2/2 \n" ); document.write( "t^2 = 100/a ---- a is acceleration due to gravity. \n" ); document.write( "Solve for t. \n" ); document.write( " |
