You can put this solution on YOUR website!
The equation of motion is:
\n" ); document.write( "\"+h%28t%29+=+-16t%5E2+%2B+50+\"
\n" ); document.write( "You want to know in how many seconds
\n" ); document.write( "the hammer will be at \"+h%28t%29+=+0+\" ft,
\n" ); document.write( "which is the ground.
\n" ); document.write( "\"+0+=+-16t%5E2+%2B+50+\"
\n" ); document.write( "\"+16t%5E2+=+50+\"
\n" ); document.write( "\"+t%5E2+=+25%2F8+\"
\n" ); document.write( "\"+t%5E2+=+3.125+\"
\n" ); document.write( "\"+t+=+sqrt%28+3.125+%29+\"
\n" ); document.write( "\"+t+=+1.77+\" sec
\n" ); document.write( "answer:: (B)
