A block of mass m= 0.1 kg is released from a height of 4m on a curved smooth surface. On the horizontal surface, path AB is smooth and path BC offers coefficient of friction μ=0.1. If the impact of block with the vertical wall at C be perfectly elastic, the total distance covered by the block on the horizontal surface before coming to rest will be :
a) 29 m
b) 49 m
c) 59 m
d) 109 m
