A block starting from rest slides down a rough fixed incline having anlge of inclination `53^(@)`.It covers 12m in first two seconds i.e from t=0 to t=2 sec then :
A. Velocity at t= 2 sec will be 12 `m//s`
B. Distance vovered in next 4 secods will be 48 m
C. coeffiec eint of friction between block & incline will be `1/3`
D. Coeffiecient of friction between block & incline will be `2/3`
