1 A particle moves in a straight line such that c Describe the motion of the particle its position in metres from a fixed origin at t = 2 seconds. is given by s(1) = 13 - 31 + 1, where t is the d At what time(s) does the particle reverse time in seconds, 1 2 0. direction? a Find expressions for the particle's e For what time interval is the particle velocity and acceleration at time I. speeding up? b Find the initial position, velocity f What is the total distance travelled and acceleration. Hence describe the by the particle between 1 = 0 and 1 = 3 particle's motion at this instant. seconds
