Self Exercise 8.4 Question 2
A particle moves along a straight line. Its displacement, s metres from the fixed point O time t is given by at time t is given by [math]s=2t^3-5t^2+4t[/math]. Find[br][br]a) the instantaneous velocity, in [math]ms^{-1}[/math], of the particle when t=2,
b) the values of t, in seconds, when the particle stops instantaneously,[br]
c) the range of values of t, in seconds, when the car moves to the right.
