oh ok I got v'(t)=6t-4
DanJS
  • DanJS
yes, the instantaneous velocity at any time, use t=3

  • chris215
ok do I plugg that into v'(t)=6t-4?
DanJS
  • DanJS
The derivative is the rate of change , with respect to time here rate of change of Distance km ... velocity km/s rate of velocity change ......acceleration km/s^2
DanJS
  • DanJS
yes, a(t) = v ' (t) = 6t - 4
