4.  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

5. Figure above shows a ticker tape chart for the motion of a trolley. The ticker tape timer was connected to a 50 Hz power supply.

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.

6. The velocity of the trolley decreased at the rate of 10 cms^-2 per second. In a displacement-time graph, the gradient of the graph represents

1. the speed
2. the distance travel
3. the velocity
4. the acceleration
