Answer:
Explanation:
Impossible to say without knowing how high point D is.
If we ignore friction, the energy converted from potential energy will exist as kinetic energy.
let d be the height in meters of point D "in the air"
mg(19 - d) = ½mv²
m is common so divides out
g(19 - d) = ½v²
v = √(2g(19 - d))
no sense in making g any more precise than the height. g = 9.8
v = √(2(9.8)(19 - d))
v = √(19.6(19 - d))
The fundamental closeness is they have a similar like charges repulse each other, distinctive charges pull in each other. While their distinction is that attractive "charges" can't be isolated. At any rate, so far it has not been accomplished. I trust this makes a difference.
