In the figure provided, three crates are connected by a string and pulley system. The mass of the crate hanging on the left side of the table is 0.550 kg and the mass of the crate on the table is 1.56 kg. If the coefficient of kinetic friction between the table and the 1.56 kg crate is 0.460, what is the acceleration of the 1.56 kg crate? Assume the string and pulleys are massless.
