Problem 1 (30 points) A block of mass m-12 Kg with initial velocity <30, 0, 0 m/s is sliding on a horizontal floor, where the coefficient of kinetic friction is equal to 0. 3. At the end, the block comes to a stop. (Take g=9.8 m/s²). What is the magnitude of the final momentum of the block? Find the magnitude of the normal force exerted by the floor on the block. ) How long will it takes to the block to come to a stop? How far does the block move?
