Asked by Elle
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?

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
