Question 48

41%

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 $x = t^3 - 15t^2 + 62t$

a.

the initial velocity of $P$ ,

[3]

b.

the value of $t\,$ for which $P\,$ has zero acceleration.
