A ski jumper travels down a slope and leaves the ski track moving in the horizontal direc-
tion with a speed of 29 m/s as in the figure.
The landing incline below her falls off with a
slope of 0 = 40°
The acceleration of gravity is 9.8 m/s².
1) Calculate the distance d she travels along the incline before landing. Answer in units of m.
2) Determine how long the ski jumper is air-borne. Answer in units of a.
3) What is the magnitude of the relative angle with which the ski jumper hits the slope?

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

True or false graphs must include scales that increase by the same amount

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 !
