Flute~~~~~~~~~~~~~~~~~~~
Explanation:
First convert the speed into m/s and time into seconds
Answer:
10.4mm
2 pages = 1 leaf
200 pages = 100 leaves
100 × 0.10 = 10 mm thickness
Total thickness = 2(0.20) +10 = 0.4+10 = 10.4mm
the more particles packed together the faster it falls
the mass + the 1 constant g-force = the speed without adding air resistance
