Sachi wants to throw a water balloon to knock over a target and win a prize. The target willonly fall over if it is hit
with a force of 0.035 N. The water balloon has a mass of 11.4 grams. How fast will Sachi have to make the water
balloon accelerate to hit the target with enough force and win the prize?
Round the answer to the nearest one tenth m/s
The water balloon must accelerate
m/s2

John throws .4 kg ball with velocity of 18 m/s. hits .2 kg bottle and bottle flies 25 m/s. how fast is ball traveling after hitting the bottle?

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 !
