1.	A block moves down a smooth inclined plane of inclination 45^@. Its velocity on reaching the bottom is v. If it slides down a rough inclined plane of same inclination, its velocity on reaching the bottom is vin, where n is a number greater than zero. The coefficient of friction mu is given by
Answer» `MU = (1-(1)/(N))` `mu =(1-(1)/(n^2))` `mu = SQRT(1-(1)/(n^2))` `mu =sqrt(1-(1)/(n))` SOLUTION :`mu =(1-(1)/(n^2))`
