Multiple-Object Accelerating Systems: Three blocks, light connecting ropes, and a light frictionless pulley comprise a system, as shown in the figure. An external force of magnitude P is applied downward on block A, causing block A to accelerate downward at a constant 2.5 m/s2. The tension in the rope connecting block B and block C is equal to 60 N.(a) What is the magnitude of the force P?(b) What is the mass of block C?
