Una pelota rueda con velocidad constante sobre la superficie de una mesa situada a 2.5 m de altura sobre el suelo. Al llegar al borde cae describiendo un lanzamiento

horizontal, si la distancia de la mesa al choque contra el piso es de 1,77 m. calcular:

el desplazamiento total de la pelota y el módulo de la velocidad.​

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 !
