Question 31

A particle moves in a straight line so that its displacement from the origin at time t t\,t seconds, t≥0t \geq 0t≥0, is x=2t3−9t2+12tx = 2t^3 - 9t^2 + 12tx=2t3−9t2+12t metres

a.

Find the velocity of the particle when t=1t = 1t=1.

[2]
b.

Find the acceleration of the particle when t=1t = 1t=1.

[2]
c.

State what your answers to parts (a) and (b) tell you about the motion of the particle at t=1t = 1t=1.
