Force and Motion - Ticker Tape (6 Questions)

This exercise consist of 6 objective questions.

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

1. constant velocity
2. decreasing velocity
3. increasing velocity

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

1. moving with increasing velocity
2. moving with constant acceleration
3. moving with increasing acceleration

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

1. 125.0 cm s-1
2. 107.1 cm s-1
3. 112.2 cm s-1
4. 105.5cm s-1

4.  The ticker-tape in Figure above was produced by a toy car moving down a tilted runway. If the ticker-tape timer produced 50 dots per second, find  the acceleration of the toy car.

1. -12.50 ms-2
2. -10.42 ms-2
3. -1.25 ms-2
4. -1.04 ms-2

5.  A trolley is pushed up a slope. Diagram above 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.

1. -100 cms-2
2. 100 cms-2
3. -80 cms-2
4. 80 cms-2

6.  Figure 2 shows a ticker tape chart for the motion of a trolley. The ticker tape timer was connected to a 50 Hz power supply.
Which of the following statements is true about the motion of the trolley?

1. The initial velocity of the trolley is 100 cms-1.
2. The average velocity of the trolley is 80 cms-1.
3. The trolley moved at a uniform deceleration.
4. The velocity of the trolley decreased at the rate of 10 cms-2 per second.
