Avase with a mass of 0.800 kilograms falls from a height of 0.750 meters to a position of 0.500 meters above the floor. ignoring frictional effects, the total mechanical energy at the 0.500 position is

E= 2 J

Explanation:

For this case we see how the mechanical energy is generated by the potential energy due to the change of position. We can express that as

E=m*g*h

Being "m" the mass of the object, "g" the value of the acceleration by gravity and "h" the distance traveled in the movement. So

E=m*g*h=0.8Kg*10m/s2*(0.75-0.5)=2J
