A1230 kg pile driver is used to drive a steel i-beam into the ground. the pile driver falls 7.07 m before contacting the beam, and it drives the beam 15.9 cm into the ground before coming to rest. find the magnitude of the average force the beam exerts on the pile driver while the pile driver is brought to rest. the acceleration of gravity is 9.8 m/s 2. answer in units of n.

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
