With the assumption of no slipping, determine the mass m of the 6-kg block which must be placed on the top of the cart in order that the system period be 0.75 s. What is the minimum coefficient of static friction for which the block will not slip relative to the cart if the cart is displaced 50 mm from the equilibrium position and released?
