A pendulum bob of mass \(m_1 = 1.0 \text{ kg}\) is attached to a light string and released from rest from a vertical height \(h = 0.80 \text{ m}\) above a horizontal floor. At the lowest point of its trajectory, the bob strikes a block of mass \(m_2 = 3.0 \text{ kg}\) initially at rest on the floor in an elastic, one-dimensional collision. The coefficient of kinetic friction between the block and the floor is \(\mu_k = 0.40\). What distance does the block slide along the floor before coming to rest?
