Question 149

A particle moves in a straight line through a point OOO.

At time t t\,t seconds, t≥0t \geq 0t≥0, the velocity of the particle is v=(t2−7t+10)v = (t^2 - 7t + 10)v=(t2−7t+10) m s−1^{-1}−1

The particle is at O O\,O when t=0t = 0t=0.

a.

Find the times at which the particle is instantaneously at rest.

[2]
b.

Find the distance travelled by the particle in the first 2 seconds.

[2]
c.
