A body falls on a surface of coefficient of restitution 0.6 from a height of 1 m. Then the body rebounds to a height of               [CPMT 1993; Pb. PET 2001]

A)          0.6 m                            

B)          0.4 m

C)          1 m                               

D)          \[{{h}_{n}}=h{{e}^{2n}}\]\[=1\times {{e}^{2\times 1}}\]= \[1\times {{(0.6)}^{2}}=0.36m\]
