12.
A car is moving with constant speed of 80 km h¹ when suddenly the driver
sees a cat 50 m straight ahead of the car. The driver's reaction time is 0.5 s and
the maximum deceleration of the car is 10 m s².
Sebuah kereta bergerak dengan kelajuan malar 80 km j¹ apabila tiba-tiba
pemandu melihat seekor kucing 50 m di hadapan kereta. Masa reaksi
pemandu ialah 0.5 s dan nyahpecutan maksimum kereta ialah 10 m s².
Calculate the total distance travelled by the car from the moment the
driver sees the cat until it stopped. What happens to the cat? [35.7 m]
Hitung jumlah jarak yang dilalui oleh kereta dari saat pemandu
(i)
(ii)
melihat kucing hingga kereta berhenti. Apa yang terjadi kepada kucing
tersebut?
Sketch acceleration against time graph to show the motion of the car.
