Guangdong Education Edition Physics Compulsory 1 (July 2005 2nd Edition) Chapter 2 to explore the law of uniform linear motion of the second section of the law of movement of free fall after class Question 5. Original title. Raindrops from the eaves drip stationary, every 0.2s drops 1 drop, the first drop of 6 drops just dripping, at this time measured the distance between the first 1,2,3,4 drops were 1.62m, 1.26m, 0.9m, as shown in Figure 1 (Assuming that the drop raindrops move exactly the same, then what is the rate at which the second drop drops?) (Assuming that the raindrops do not take air resistance into account)
