What motion could be represented by this = length of=20 ticker tape?
    1 A trolley moving on a circular track.
    2 A trolley moving at a uniform velocity.
    3 A trolley moving freely up an inclined = runway.
    4 A trolley pulled by a rubber band stretched to a constant = length.
2.) The diagram below shows a portion of a length = of ticker=20 tape obtained in an experiment in which a trolley, with the ticker = tape=20 attached, was pulled along by a constant force.

The experimenter wanted to calculate the = instantaneous=20 velocity of the trolley when the mark labeled B was made. If the = period of=20 vibration of the timer was T, which of the following correctly gives = the=20 instantaneous velocity at B?
    1 AC/T
    2 AC/2T
    3 BC/T
    4 AB/T
