what is the velocity of a car riding at 10 m/s after 4 seconds of experiencing a constant acceleration of 2 m/s? After these 4 seconds the car maintains a constant velocity. What is this velocity?

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

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 !

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
