A 3.0 kg particle moves along an
x-axis, being propelled by a variable force directed along that axis. Its position is given by
x
=3.0m+(6.0(m)/(s))t+ct^(2)-(2.0(m)/(s^(3)))t^(3)with
xin meters and
tin seconds. The factor
cis a constant. At
t=2.0s the force on the particle has a magnitude of
35Nand is in the negative direction of the axis. What is
c? Number Units
