Question

Basic Physics roblem 3.85 Part A Some plants disperse their seeds when the fruit splits and the seeds through the air. The trajectory on one type of plant, seeds are projected at Which of these hypotheses is best supported by the data? of these seeds can be determined with a high-speed camera In an e 20 cm above ground level with initial speeds between 23 m/s and 4.6 m/s The launch angle is measured from the horizontal, with +90" corresponding to an initial velocity straight up and-90 straight down. A large number of seeds are observed, and their initial launch angles are recorded O Seeds are preferentially launched at angles that maximize the height they travel above Seeds are preferentially launched at angles below the horizontal in order to drive the se Seeds are preferentially launched at angles that maximize the horizontal distance the s Seeds are preferentially launched at angles that minimize the time the seeds spend exp The range of projection angles is found to be -51 to 65 between 6 and 56" (See W.J. Garrison et al in two species", Amer Request Answer J Bot Sept 2000, 87:9, 1257-64) Provide Feedback O Type here to search SONY

Explanation / Answer

Answer is option c . The plant wants to disperse the seeds as far as possible meaning to get the maximum range . Hence horizontal displacement should be maximum .
