A scooter starts from rest at a traffic signal and travels along a straight road according to the following schedule:
Stage 1: It accelerates uniformly for 4s with a1=3m/s2.
Stage 2: It then continues with the speed reached at the end of stage 1 for the next 6s.
Answer the questions below. Take the direction of motion as positive.
(i) Calculate the speed of the scooter at the end of the first 4s.
(ii) Find the displacement covered during stage 1.
(iii) Determine the displacement covered during stage 2.
(iv) Obtain the total displacement for the entire 10s journey and sketch a labelled velocity–time graph for the motion.
