Question 24

A particle P P\,P travels along a straight line through a point O O\,O so that at time t t\,t s after passing through O O\,O its displacement from O O\,O is x x\,x m, where x=t2(t2−4t+4)x = t^2(t^2 - 4t + 4)x=t2(t2−4t+4)

a.

Show that P P\,P will never move along the negative xxx-axis.

[2]
b.

Find the times when P P\,P is instantaneously at rest.

[5]
c.
