An object is dropped from 20m. It is 1kg and the Fgrav = 10 N / kg. What is its speed right before landing?

Not sure what information to use, or really how to use it. Its just a simple falling objects question. Thanks.An object is dropped from 20m. It is 1kg and the Fgrav = 10 N / kg. What is its speed right before landing?
hg = 1/2 v^2


solve for v





20 * 10 = 1/2 v^2


v= 20 m/s





notice the absence of mass as it should beAn object is dropped from 20m. It is 1kg and the Fgrav = 10 N / kg. What is its speed right before landing?
32 feet per second/second...
