A ball is shot from the ground into the air. At a height of 9.1 m, the velocity is observed to be v = (7.6 + 6.7 ) m/s, with horizontal and upward.
(a) To what maximum height does the ball rise?
(b) What total horizontal distance does the ball travel?
(c) What is the magnitude of the ball's velocity just before it hits the gound?
(d)What is the direction of the ball's velocity just before it hits the ground?

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 !

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
