A block of mass m is placed on the top of a 6kg cart such that the time period of the system is 0.75 s assuming there is no slipping. If the cart is displaced by 50 mm from its equilibrium position and released, then the coefficient of static friction `mu_(s)` between block and cart is just sufficient to prevent the block from sliding. The value of m and `mu_(s)` respectively are (Take `g = 9.8 m//s^(2))`
