A mathematical problem
A light string ABCD has one end fixed at A, passes under a movable pulley of mass M at B, over a fixed pulley C and carries a mass M' at D. The parts of the string are vertical. Show M descends with acceleration g(M-2M')/M+4M'
g=9.8 m/s2 |

surely descent would be a physics problem? the rate at which an object changes its velocity due to acceleration? which would change from planet to planet, and seeing as youre using gravity as 9.8 m/s2 im guessing the planets earth?
