QUESTION 3
(a) The position of a particle moving on a smooth horizontal floor is given as a function of time
according to the equation x = ut + --at?. At timet = 0, the particle has velocity u. Obtain an
expression for the velocity of the particle as a function of time. Hence, find the value of this
velocity after 8 seconds given that the initial velocity u is 5.0 m/s.
