Unformatted text preview: Quiz 5B A B B For the Blocks shown above, if the coefficient of kinetic friction is 0.50 and mass A is 50kg, what value of mass B is needed to provide a constant velocity for the coupled system if it is set into motion? Answer: Constant velocity => a=0 for each mass. Thus, ∑F=0 for each mass. T B W ∑F=T ­W=0 => T=MBg And, T= MBg Therefore, MB=µkMa = 0.5(50) Kg = 25 Kg N  ­K A W ∑Fy =0 => N=W T ∑Fx =0 =>...
