Two objects are connected by a string with a mass less, friction less pulley. The coefficient of friction is .298. The block on the table is 4 kg. What must the mass of the hanging block be so that the block on the table will move with a constant speed?

  • Physics - ,

    Make the mass of the whole a function of vbr then derive.

    Solve:

    vbr{lr<5vvx><f(nn)/.bbn>
    vbr<lr><5.12>(9.8)^3
    .bbn=%ff
    %ff=F(9x)
    .bbn=%ff9x
    .bbn=.133%tri
    .bbn=.tri
    t.ri=vbr
    v=31.4
    b=59.3
    r=28.6
    mass= __ kg
