The speed vms- of an object at time t seconds is modelled by the differential equation
de =-kv(4+12),
where k is a positive constant. initially, v = 4.
(i) find constants a, b and c such that –
v(4 +12v
4 +12
(ii) hence show by integration that v =
_
4
(iii) after 1 second the speed of the object is 2 ms. find the value of k.
