5. A tape attached to an accelerating trolley passes through a ticker that makes dots on it at a frequency of 50Hz The ticker timer makes 10 dots on a 10cm long tape such that, the distance a between the
first two dots is 0.5cm and the distance b between the last two dots is 1 5cm
(a)Determine the velocity of the trolley at:
I Distance a
II Distance b
Determine the acceleration of the trolley.
(6) State with a reason what would be observed on the spacing between the dots on the tape when
the trolley is made to move on a horizontal surface.
