Problem 6P

•A dart leaves the barrel of a blowgun at a speed ?v?. The length of the blowgun barrel is ?L?. Assume that the acceleration of the dart in the barrel is uniform. a. Show that the dart moves inside the barrel for a ? b. If the dart’s exit speed is 15.0 m/s and the length of the blowgun is 1.4 m, show that the time the dart is in the barrel is 0.19 s.

Step-by-Step Solution:
Step 1 of 3

(a).Here at initial v = 0 and in the final v = v i f If we draw a graph of v v/s t graph is linear.it means constant acceleration. Consider v avg = v/2 L = v avg * t Then t = L/v avg t = L/(v/2) t = 2L/v Hence the dart moves inside the barrel for a time of t = 2L/v (b).To show that the time the dart is in the barrel is 0.19 s. Consider from above figure x x = 1f4 m i 2 l = vi+ 1/2 at 1 v = v + at 2 f i Eq 2 becomes 15 m/s = 0 + at a = 15/t in eq 1 2 l = v i 1/2 at 1 2 1.4 m = 0 + 1/2(15/t)t 1.4 m = 7.5 t t = 0.1866 s~0.19 s
