An Object falling from rest covers distance of d = 9800t²mm in t seconds.
\n" ); document.write( " Solve this equation for t and determine how many seconds it takes for an object to fall 22,050 mm.
\n" ); document.write( ":
\n" ); document.write( "Replace d with 22,050
\n" ); document.write( ":
\n" ); document.write( "9800t^2 = 22050
\n" ); document.write( "t^2 = $\"22050%2F9800\"$
