Consider the crates in the figure where m1 = 45 kg and m2 = 12 kg. Assume that there is no friction between m1 and the table.
(a) Make a sketch showing all the forces on the crates. Include a coordinate system.
(b) Determine the components of the forces along the coordinate axes.
(c) Write Newton's second law for motion along both coordinate directions.
(d) Solve the equations from part (c) to find the acceleration of the crates and the tension in the string.
