(ii) Set-up the apparatus as illustrated in the diagram above, such that the clamp is 1.5 m above the floor. (iii) Tie one end of the thread to the pulley. (iv) Tie the other end of the thread to the hanger. (v) Slot a mass m = 50 g on the hanger. (vi) Wind the thread around the groove of the pulley until the base of the hanger is at a height h = 1.4 m above the floor. Maintain this height h for every other value of m throughout the experiment. (vii)Release the mass to unwind the thread (viii) Determine and record the time t taken by the mass m to reach the floor. (ix) Evaluate t2 (x) Also evaluate a = , T = (10 – ) and = (xi) Repeat the...
