/* write a program to find out velocity of a free fall object from a specific height.
des: as input you will give an floating number as height.. value should not exeed 0<X<250
and out put will be a single floating number with 2 decimal points.
Note: object will fall from a Stable condition. and earth g=9.8m/s2 */
