9. ### For positive constants k and g, the velocity, v , of a particle of mass m at time t is given by?

a = dv/dt = mg/ k *(- k / m )*e^(kt/ m ) = -g*e^(kt/ m ) at t = 0 the rate of change a = -g = -9.8m/s^2 at t = 2 then a = -g*e^(2k/ m ) This means that the velocity is reducing since the value of a is negative
