Linear Motion / Gerakan Linear 3

The diagram shows a strip of ticker tape that has been pulled by a moving trolley. The trolley is moving with:

Rajah menunjukkan sehelai potongan pita detik yang ditarik oleh sebiji troli. Troli tersebut sedang bergerak secara:

• Constant Velocity

  
  

  Halaju Malar

• Decreasing Velocity

  
  

  Halaju menurun

• Increasing Velocity

  
  

  Halaju bertambah

The figure shows a ticker tape chart for the motion of a trolley. We can conclude that the trolley is :

Carta graf menunjukkan keratan pita detik. Carta graf trolli tersebut menunjukkan bahawa trolli sedang bergerak dengan:

• Moving with increasing velocity

  
  

  Bergerak dengan halaju yang sedang meningkat

• Moving with constant acceleration

  
  

  Bergerak dengan pecutan yang seragam

• Moving with increasing acceleration

  
  

  Bergerak dengan pecutan yang sedang meningkat

Figure shows a strip of ticker tape that has been pulled by a moving trolley. The ticker tape was vibrating at 50 Hz. Find the average velocity of the trolley:

Darjah menunjukkan satu keratan pita detik yang ditarik oleh trolli. Pita detik sedang bergetar dengan 50 Hz. Cari halaju purata trolli tersebut:

• 125 cms^-1

• 107.1 cms^-1

• 112.2 cms^-1

• 105.5 cms^-1

The ticker tape in figure was produced by a toy car moving down a tilted runway. If the ticker tape produced 50 dots per second, find the acceleration of the toy car:

Jangka masa detik dalah rajah akibat ditarik oleh kereta mainan yang bergerak ke bawah landasan. Jika pita detik menghasilkan 50 titik setiap saat, cari pecutan kereta mainan tersebut:

• -12.5 ms^-2

• -10.42 ms^-2

• -1.25 ms^-2

• -1.04 ms^-2

A trolley is pushed up a slope. Diagram shows ticker tape chart that show the movement of the trolley. Every section of the tape contains 5 ticks. If the ticker tape timer produced 50 dots per second, determine the acceleration of the trolley:

Sebuah trolli ditolak atas satu landasan. Rajah menunjukka satu carta jangka masa detik. Setiap keratan mempunyai 5 detik. Jika pita detik menghasilkan 50 titik setiap saat, Cari pecutan trolli:

• -100 cms^-2

• 100 cms^-2

• -80 cms^-2

• 80 cms^-2

The graph below shows how the displacement of an object changes with time. Which of the following is NOT TRUE regarding the motion of the object ?

• The object is moving with uniform acceleration

  
  

  Objek bergerak dengan pecutan yang seragam

• The object is moving in the negative direction

  
  

  Objek bergerak di arah negatif

• Velocity of the object is negative and constant

  
  

  Halaju objek ialah negatif dan seragam

• The speed of the object is constant

  
  

  Laju objek ialah seragam

The diagram shows how the displacement of car varies with its time of travelling. What is the velocity of the car ?
