A particle, P, moves along the x-axis. At time t seconds, t > 0, the displacement, metres, of P from the origin O, is given by x = 1/2t^2 (t^2 – 2t +1)
P is instantaneously at rest when t = 0, t = 1/2 and t = 1.
Find the total distance
travelled by P in the time interval 0 Input note: give your answer in exact form.
(Note: < and > are greater or equal and less or equal)
