A log is floating on swiftly moving water. A stone is dropped from rest from a 75-m high bridge and lands on the log as it passes under the bridge.
\n" ); document.write( "(a) What is the velocity of the stone when it lands on the log?
\n" ); document.write( "Using 10 m/sec/sec for gravity:
\n" ); document.write( "----
\n" ); document.write( "s = at^2/2 = 75
\n" ); document.write( "5t^2 = 75
\n" ); document.write( "t = 5 seconds to impact.
\n" ); document.write( "v = at = 10*5 = 50 m/sec
\n" ); document.write( "===================
\n" ); document.write( "(b) How long does it take the stone to reach the log?
\n" ); document.write( "5 seconds as in (a)
\n" ); document.write( "---------------
\n" ); document.write( "(c) If the log moves with a constant speed of 5.0 m/s, what is the horizontal distance between the log and the bridge when the stone is dropped?
\n" ); document.write( "----
\n" ); document.write( "Find the hypotenuse with sides of 25 & 75 meters
\n" ); document.write( "
\n" ); document.write( "
\n" );
