(I'm not sure what the unit "m1" is. Do you mean ml for milliliters? I am going to use ml in this problem.) Volume= 130ml Mass= 585g The formula for density is Density=Mass/Volume All you have to do is pop the information in the formula Density= 585g/130ml 585/130= 4.5 you can't divide g/ml, so just leave it the way it is Therefore the answer is Density= 4.5 g/ml Hope this helps!
We use conservation of energy. Note that at the beginning of the drop, the pig has only potential energy, and at the bottom, it has only kinetic energy. Then:
