A luggage handler pulls a 20.0 kg suitcase up a ramp inclined at 25 degrees above the horizontal by a force F of magnitude 145 N that acts parallel to the ramp. The coefficient of kinetic friction between the ramp and the incline is = 0.30. If the suitcase travels 4.60 m along the ramp, calculate:A) the work done on the suitcase by force F. B) the work done on the suitcase by the gravitational force. C) the work done on the suitcase by the normal force. D) the work done on the suitcase by the friction force. E) the total work done on the suitcase. F) if the velocity of the suitcase is zero at the bottom of the ramp, what is its velocity after it has travelled 4.60 m along the ramp.

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 !
