Figure 1 shows how the student set up the apparatus. Figure 1 0 1 . 1 Before attaching the mass holder the student placed the trolley at the top of the runway. The trolley rolled down the runway without being pushed. What change to the apparatus in Figure 1 could be made to prevent the trolley from starting to roll down the runway? [1 mark] Tick () one box. Move the wooden block to the left. Shorten the length of the runway. Use a taller wooden block. 0 1 . 2 The student attached the mass holder to the string.
