An object is dropped from some height and takes 5.5 seconds to hit bottom when it hits the bottom it's going out a velocity of 53.9 M/sec what is its acceleration

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

the answer to this is proletariats.

hope this : )

you can cut your hand off if your not
