Question

(20%) Problem 2: While watching the clouds pass by, you notice a European swallow flying horizontally 20.9 m above you. When the swallow is directly overhead, it drops a m1 = 11.8 kg coconut. From your ornithological studies, you know that the air-speed of this particular species of swallow while carrying such a load is vo = 7.98 m/s Randomized Variables h=20.9 m m=11.8kg O= 7.98 m/s +X ©theexpertta.com 20% Part (a) Calculate the magnitude of the angular momentum L of the coconut in kg-m2/s as observed by you at the moment that it is released directly overhead 20% Part (b) Develop an expression for the x component of the radius vector rx(t) (in meters) of the coconut with respect to you as a function of the given information, the free-fall time t, and variables available in the palette. Let t-0 be the moment that the coconut is released Express vour answer in unit vector notation Grade Summary Deductions Potential 4(1) = 11 0% 100% 789 Submissions Attempts remaining: 3 (5% per attempt) detailed view

Explanation / Answer

A) L = m*vo*h = 11.8*7.98*20.9 = 1968.0276 kg*m^2/s

B) rx(t) = vo*t
