En un balde mezclamos 3 litros de agua con 2 kg de cemento ¿cual es la densidad de la mezcla?​

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Will you chech and finish these for me, because i am stumped with them.

Which object is most likely represented by a dot?
