the acceleration of a particle moving in a straight line after time t s is given by
a =8-4tms^-2. If the particle started at rest 2m from 0, find:
1) The velocity and displacement as functions of time
2) the time when the particle is stationary and the displacement at this time.
3) the total...
the number of ants in a colony is given by p = 12 + 11t - t^2, where P is the number of ants, in thousands, after t days from 1st of july.
1) find the rate of change of the population P with respect to time t.
2) find the rate of change of the population and the total population initially.
3)...
an ice with an edge of 5cm melts at constant rate. If the edge measures 3cm after 2 hours and the ice remains cubical, find:
1) the rate at which the ice cube melts.
2) the volume at any time t
3)the time needed to melt the ice cube completely
