A stone is dropped from a height of 25 meters. a) How long will it take for the stone to hit the ground? b) What velocity does it have when it hits the ground?

a golden breast plate weighing 18.63 kg in dropped in a that initially contains water. after the breast plate was totally submerged, the water level rises by 61 87cm. the tub has a diameter of 6 centimeters and the breast plate was said to be mare only from gold and silver. compute for the percentage of each component of the breast plate if the density of gold is 19,3 g/cubic centimeter and silver has a density of 10.49 g/cubic centimeter.
