    A student investigates the effect of unbalanced force on the acceleration of a trolley, using the apparatus shown.

    Apparatus: beaker (Ramp (bench)), conical flask (Trolley), test tube (Pulley)stringRamp (bench)TrolleyPulley
    Trolley on a sloping ramp, pulled by a hanging mass over a pulley.
    (a)

    Describe how the student could measure the acceleration of the trolley in this experiment.

    [2 marks]
    (b)

    The mass of the trolley and the hanging weights is 1.8 kg. If the total unbalanced force is 5.4 N, calculate the acceleration of the trolley.
