If the answer is 2.8, -2.8 or -8.4, it is not CORRECT
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?
