A block of mass `m=0.1kg` is released from a height of 4 m on a curved smooth surface. On the horizonal surface, path AB is smooth and path BC is rough with a coefficient of friction `mu=0.1`. If the impact of the block with the verical wall at C is perfectly elastic, the total distance covered by the block on the horizontal surface before coming to rest will be (take `g=10ms^(-2)`)

Options

A. 29 m
B. 49m
C. 59m
D. 109m

Answer

C
