consider a system consisting of a rough surface, three masses, two massless strings, and a massless and frictionless pulley. The mass of each block is ma = 25 kg, mb = 18 kg, and mc = 10 kg. The static and kinetic friction coefficients are 0.75 and 0.25 respectively for all surfaces. For parts a and b the masses are given a quick push so that ma is initially moving downwards. a) calculate the magnitude of the acceleration of ma b) is ma slowing down or speeding up? Explain c) calculate the tension in the string between mc and mb. calculate the tension in the string between mb and ma.
