A particle $P\,$ travels along a straight line through a point $O\,$ so that at time $t\,$ s after passing through $O\,$ its displacement from $O\,$ is $x\,$ m, where $x = 2t^3 - 18t^2 + 48t$

a.

the times when $P\,$ is instantaneously at rest,

[3]

b.

the total distance travelled in the first 5 seconds.
