A cart of mass m A sliding with friction on a horizontal rail will be pulled by a suspended mass (of mass m B), the two objects being connected by a rope passing through a pulley (see photo). The goal is to modelize an equation that describes friction using system dynamics. find an equation giving the modulus of kinetic friction (fc) under the horizontal slider in motion when it is braked, ie subjected only to friction. Then test your model for the kinetic friction coefficient uc and its uncertainty for this phase of motion using the following values: We use g = (9.81 ± 0.01) m/s^2 as usual. mA = (0.375 ± 0.005)kg; mB = (0.23 ± 0.004) kg; a= (3.52 ± 0.15) m/s^2;
