A block is released from height `(ne 0)` on a rouch track AB as shown in figure. Coefficient of friction between the block and the surface is `mu = 0.5`. Track BC is smooth. From C onwards there is a circular smooth track of radius R = 50 cm
For what value of `h` block does not leave contact with any surface ? Given, `tan theta = (3)/(4) and g = 10 m//s^(2)`
A. h=2.5 m
B. `h le 2.0` m
C. h = 2.0 m
D. `h le 1.5` m
