Question

On a Mythbusters episode, the impact of large birds on an airplane windshield was studied. They constructed a tube to accelerate the bird (a frozen chicken) By using high pressure gas and tube, it is computed that the position of the "bird" in the tube is given by x = (1.1 x 10² m/s)t + (6.9 x 10³ m/s²)t² - (8.9 x 10⁴ m/s³)t³. The bird leaves the end of the barrel in 0.025 s after firing. (a) What is the length of the barrel? (b) What is the speed of bird when it leaves the barrel? (c) What is the net force on the bird at (i) t = 0.0 s, (ii) t = 0.012 s, (iii) t = 0.025 s? m_bird = 500 g   {a. 5.67 m, b. 288 m/s}
