(ii) Plot a velocity-time graph for the car. Plot graf halaju-masa untuk kereta tersebut. [3 marks] [3 markah] (111) Calculate the total distance travelled by the car. Kira jumlah jarak yang dilalui oleh kereta. [4 marks] [4 markah](d) A mini car starting from rest accelerates uniformly to reach velocity of 72 km/h after 10 s. It continues at this velocity for 10 s. It then accelerates again to reach 45 m's after a further 15 s. Then it starts to decelerate for 4.5 m/s' until it rests. Sebuah kereta mini bergerak dari rehat dengan pecutan sekata untuk mencapai halaju 72 km/j selepas 10 s. la meneruskan perjalanan dengan halaju tersebut bagi 10 s berikutnya. Kemudian ia memecut lagi hingga mencapai kelajuan 45 w/'s selama 15 s. Seterusnya ia mula nyahpecutan untuk 4.5 m/s' hingga kereta tersebut berehat. (i) Calculate the time taken for the car to totally rest. Kirakan masa yang diperlukan untuk kereta tersebut rehat sepenuhnya. [3 marks] [3 markah]
